Engine Cylinder Head: Features and Operations for Peak Efficiency

Any internal combustion engine’s cylinder head is a complex but essential thing that influences the car’s overall performance. The cylinder head’s layout phase is essential because of its crucial characteristic. One unique stationary aspect of all internal combustion engine types is the cylinder head.

It is located on the pinnacle of the engine and is secured to the engine block by captive or important screws, which give specific sealing and calibration. It is the engine thing that is maximum closely loaded.

Its primary feature is to surround the cylinder top, and the high temperatures and pressures it consists of are dangerous to its element parts. The cylinder head’s technical problems jeopardize the engine’s normal overall performance.

What Does a Cylinder Head Look Like?

The cylinder head, along with the injector holders and spark plug sockets, forms the top roof of the combustion chamber above each piston. The cylinder head is where the intake and exhaust duct hoses meet, along with the corresponding guides, valves, and return springs.

Often, one or two camshafts, bucket tappets, or rocker arms are supported by the top part. The ducts needed for coolant circulation are also part of the cylinder head. The cylinder head serves as thermal insulation in addition to obstructing the cylinders since the exterior side must stay reasonably cold while the engine side can reach temperatures of up to 300°C.

Its design necessitates a significant amount of time, substantial mechanical sector knowledge, and exceptional precision in the implementation of the many parts because it is an engine component of such complexity and importance.

Angular Tightening Bolts

Most modern engines have angular tightening bolts, which don’t need to be tightened. Because these bolts are made to be stretched plastically, they may readily conform to the technical criteria provided by the manufacturer. When all bolts are fitted, a little torque (Kpm) is applied gradually, resulting in uniform tension across the seal.

After disassembly, the angular tightening bolts are permanently distorted since they are employed in the elastic area. Reusing these bolts will prevent the bolts from breaking and prevent the same and proper tightening tension from being applied. Thus, it is imperative that these bolts never be utilized again.

Things to Keep an Eye Out for

New Bolts

Our experts advise against reusing angular tightening nuts. Additionally, our own label offers a selection of head bolts at a competitive price-to-quality ratio. It is not feasible to reuse a head gasket, much like head bolts.

Instructions from the Manufacturer

It is crucial to precisely tighten and fit cylinder head bolts in accordance with the specifications in order for the bolts to function as intended. If this is not done, there might be more serious sealing issues like leaks. Inadequate sealing and damage might also result from overtightening bolts.

Tightening Sequence

It’s crucial to install cylinder head bolts with angle tensioning in the precise sequence that the manufacturer specifies. If the tightening criteria are not followed, the cylinder head or cylinder block may experience leakage, early head gasket failure, undesired stress, deformation, or cracking.

Mounting Supplies

A torque spanner may be used to tighten bolts with a regular head, while an angular rotation gauge is better for tightening bolts with an angle.


There also are numerous widespread head bolts available to be used in overall performance.
For example, ARP offers a wide variety, together with their popular “head-studs,” which have a unfastened threaded stop with nut. The emblem makes use of a unique kind of steel that has tremendous electricity within the elastic area.

How to Tighten Cylinder Head Bolts

A beneficial step-through-step academic for becoming cylinder head bolts is obtainable through our experts. When tightening cylinder head bolts, make sure you have examined the manufacturer’s instructions first.

Steps to Install Cylinder Head Bolts

  1. Make sure you smooth the cylinder head and surrounding regions absolutely.
  2. Ensure that all remaining particles and gaskets have been removed to prevent troubles.
  3. Check the floor’s levelness in phrases of length and breadth the use of a ruler or row
  4. Make sure that at a specialised workshop, any grooves, scratches, deformations, or different choppy areas had been removed.
  5. Verify that the engine block and cylinder head dimensions, as well as the gasket’s thickness, correspond to the manufacturer’s hints.
  6. Use compressed air, as an instance, to clear the bolt holes’ threads of any grease, water, or other impurities.
  7. Without any sealants, grease, or oil, area the pinnacle gasket at the engine block.
  8. For similar data, see our weblog post approximately putting in cylinder head gaskets.
  9. Next, replace the cylinder head with a warning in order no longer to harm the gasket.
  10. Make positive you constantly use sparkling head bolts.
  11. Turn it round and grease the bolt threads and the bottom of the top with a touch oil using an oiled cloth.
  12. The manufacturer’s washing machine needs to also have its sides lightly greased if one is utilized.
  13. As continually, examine the manufacturer’s instructions before tightening the bolts. This is because of the opportunity of versions no longer simply between manufacturers but also among distinctive engine kinds.
  14. Use simplest corrosion inhibitors and antifreeze that have been certified and encouraged.

This engine, which is sometimes called the “Ford powerstroke diesel,” has unparalleled power and performance. It has a lengthy history as well. Now that you know all there is to know about Ford’s renowned Powerstroke diesel, let’s determine if this is the best engine option for you.

Which Ford Trucks Offer the Power Stroke Diesel?

Depending on the model, Ford Powerstroke diesel engines are either standard or available equipment on Ford Super Duty trucks, ranging from the F-250 to the F-550.

Power and Capacity

Some Ford trucks from the 2023 model year are outfitted with the third-generation 6.7L Ford PowerStroke V8 Turbo Diesel engine, which can produce up to 1,050 lb.-ft. of torque at 1,600 rpm and 475 horsepower at 2,600 rpm.

When was Ford Powerstroke Released?

Over around thirty years, the Ford Powerstroke Diesel engine has undergone continuous development and refinement! 1994 was the model year of its initial introduction.

This original 7.3L Powerstroke engine was nothing short of groundbreaking in its day, according to MotorTrend:

With 210 horsepower and 425 lb-ft of torque in 1994, Power Strokes really transformed the diesel industry in terms of power, replacing the IDI turbo figures of 190/390. The 1994 Cummins (Dodge RAM) produced 175 horsepower and 420 lb-ft of torque, while the GM 6.5L (Chevy Silverado) produced 180 horsepower and 360 lb-ft of torque, to further put the mid-1990s turbodiesel scene into context.

Released in 2003, the 6.0L Ford Powerstroke engine represented a significant advancement in fuel injection technology, exhaust gas recirculation, and responsiveness with its all-new variable-geometry turbocharger.

The Ford 6.7L Powerstroke, which debuted in the 2011 model year, is more closely similar to the Powerstroke diesel engines of today.

Know All About Duramax Head Gasket Replacement

Duramax has had several classifications since its launch, including LBZ, LLY, LBZ, LMM, and LML. Several changes were made along the road. All versions are rather dependable, however the older LB7 engines from 2001 to 2004 and the LLYs from 04 to 2005 are beginning to show their age. These earlier model vehicles frequently have blown head gaskets because of excessive mileage, aftermarket tune, and general wear and tear.

We started with learning the inside scoop on changing Duramax head gaskets correctly. The vehicle in question was a ‘04.5 LLY that required a new head gasket because of excessive hauling and a high tune.

The truck had begun to use coolant; it was almost a quart every week at first. The truck was taken under the knife right away since it was obvious that something had to be done quickly to prevent any further injuries.

One thing to keep in mind is how labor-intensive replacing the head gasket on a Duramax is. With a book time of around 40 hours of effort, the labor alone often costs close to $4,000.

Step-by-Step Duramax Head Gasket Replacement Process

1. Draining the coolant and removing the top fan shroud are the initial steps in replacing the Duramax head gasket. Fortunately, one item that may still be left in place is the radiator.

2. Take care to replace everything just as it was taken apart, even the fan belt. Similar to tires, belts too exhibit a wear pattern.

3. To remove the cylinder heads, almost all of the engine’s accessories must be taken off. This comprises the idler bracket and pulleys (shown), the alternator, and the air conditioner compressor (which is just movable to the side).

4. Eliminate systems in their whole system whenever feasible to save time. Despite appearances to the contrary, everything can be fully wrapped around the driver’s side charge pipe without removing anything from the driver’s side head.

5. It should be possible to remove the top hard hose and coolant crossover at this point as all of the coolant should have drained out.

6. It was now time to tackle the wire harness on the passenger’s side of the engine, as the front was beginning to fall apart. This has to be (gently) removed in order to reach the engine’s upper valve cover.

7. Then take off the EGR system. There appears to be a significant quantity of buildup, which has to be removed before the system is reinstalled.

8. It was now possible to work on the injectors, lines, and top valve covers once the EGR and wiring were removed.

9. The engine’s injector lines, injector harness, glow plugs, and injectors had to be taken out before the upper valve cover could be removed. For this task, one of the few specialized instruments required is an injector puller.

10. The engine’s valve train may be seen once the lower valve cover has been removed, following the removal of the upper valve cover.

11. Now work on the driver’s side of the engine after finishing the passenger side, repeating the process with the wiring, glow plugs, lines, and injectors. Now that both valve covers were removed, the engine’s valve train needed to be disassembled, beginning with the rocker arm assembly.

12. It has been a lengthy journey, but the cylinder head has to be taken out! It is evident that the driver’s side back bottom bolt cannot be removed without contacting the firewall. The secret is to simply undo the bolt and extract it concurrently with the head removal.

13. It’s time to take off the heads! With the removal of the passenger and driver’s side heads, the engine is reduced to a simple short block with a turbocharger.

14. The deformed region where the stock head gasket broke and substantial volumes of coolant leaked was easily visible upon close inspection.

15. We always advise against reinstalling factory heads before having them examined and surfaced. We received both cylinder heads and had them surfaced, cleaned, and inspected for cracks. After just minimal adjustments were made, both heads returned to their original appearance.

16. It was time to clean the decks on the block and replace the gaskets and heads as the engine bay appeared to be quite empty.

17. Employ a full head gasket kit for reinstallation. Two multi-layer steel (MLS) gaskets and all the other gaskets and hardware required to finish the project are included in this package.

18. This kit also comes with a fresh set of head bolts to replace the factory hardware that is ten years old. ARP studs “weren’t needed in this application,customers can still upgrade to them.

19. It was now time to go to the passenger’s side head torque once the driver’s side had finished. After the installation of both cylinder heads, the valvetrain needed to be put back together.

20. The rocker arms cannot be simply installed and removed. Before putting the engine’s remaining components together, each valve must be re-adjusted to meet factory lash specifications.

21. The engine’s injectors and upper and lower valve covers may be added after the valvetrain is in place. One of the first things we install is the glow plugs and injectors to prevent further junk from entering the engine.

22. It was beginning to resemble an engine once more with the installation of the freshly machined heads, valve covers, and valvetrain! Sadly, there was still more work to be done due to the Duramax engine’s complexity.

23. Do you recall the first fifteen stages of disassembly? All that had been taken off now had to be put back on. On the Duramax engine, everything fits and installs in a certain order. You’re most likely doing something incorrect if it doesn’t feel comfortable when you put it back on.

24. This second image shows you just how many parts must be replaced in order for the engine to start up again. After working on the engine for three to four hours from the valve cover-on point, the engine was prepared for the last few intake, exhaust, and coolant components.

25. Every time we work on an LLY, we always propose an intake upgrade because the stock intake is highly restricted. When compared to the factory version, which chokes out the turbo at heavy loads, this S&B component is a huge improvement.

6.7 Powerstroke Vs. 6.7 Cummins – Which One is Better?

As much a part of truck and vehicle culture as racing and motorsports have ever been, brand loyalty goes hand in hand with these activities. Everybody has a favorite car, and diesel-powered vehicles are no exception. There are several explanations for this.

Regarding trucks, a lot of enthusiasts seem to favor RAM’s 6.7 Cummins and Ford’s 6.7 Powerstroke. Because of their popularity, a lot of aftermarket performance parts have been created to extract every last bit of torque and horsepower from these two engines.

The Growing Adoption Of Diesel Trucks

In the US, diesel-powered automobiles have long been widely used in both commercial and industrial settings. Diesel power plants have long been used by trucks, heavy machinery, tractors, and other equipment that requires enormous torque, but it has taken some time for diesel-powered passenger cars and medium-to light-duty trucks to gain popularity in the United States.

Since the 1960s, diesel vehicles have gained popularity in Europe, mostly due to their increased fuel efficiency when equipped with smaller engines and their superior performance when equipped with larger, turbo diesel engines.

Although diesel-powered vehicles have made occasional appearances at prestigious races in the U.S., such as the Indy 500, it is European manufacturers who have truly harnessed the power of diesel technology.

Through the use of turbo diesel engines, these manufacturers have emerged victorious in renowned international racing competitions like the 24 Hours of Le Mans and the 12 Hours of Sebring. These grueling endurance races have served as a platform for manufacturers to showcase their technical advancements over the years, solidifying the reputation of diesel engines as both robust and efficient.

6.7 Cummins

With a rich history dating back to 1919, Cummins has established itself as a reputable manufacturer with a primary focus on industrial power plants. By 1984, they had expanded into the production of their B series engine, which quickly gained popularity in a variety of vehicles, ranging from school buses to light-duty trucks.

Combining reliability and power, the B series, available in both four and six-cylinder options, has been the top choice for diesel engines in Dodge/RAM trucks since 1989. Boasting a turbocharger and gear-driven camshafts, Cummins engines are known for their durability. As the exclusive diesel engine provider for Dodge/RAM pickup trucks, Cummins has garnered a dedicated following among the Mopar community.

In 2007, the 6.7l Cummins engine was introduced, replacing the 5.9 ISB Cummins. This was a highly anticipated change due to the significant increase in engine size, with a displacement of 408.2 cubic inches. It became the largest straight-six diesel engine available for light-duty trucks.

This new powerhouse marked a shift from turbocharged engines to the inclusion of variable geometry technology. This advancement not only resulted in reduced turbo lag, but it was also integrated into the exhaust brake system. The 6.7 has certainly set a new standard for Cummins light-duty truck engines.

6.7 Powerstroke

Ford has relied on the Powerstroke as its top diesel engine for their trucks since 1994. Originally manufactured by Navistar, a company linked to International Harvester, Ford took over production in 2011. Since then, all Powerstroke engines have been meticulously designed and created by Ford themselves. Typically, V-8 engines have been used for larger trucks, while smaller five-cylinder engines have been crafted for models such as the Ford Ranger.

In 2008-2009, the Ford 6.7l Powerstroke underwent significant development and became the first vehicle to hit the market in the 2011 model year. Its impressive design boasts a 90° V-8 engine, equipped with a single Garrett turbo and four valves per cylinder. The use of aluminum heads further enhances its performance.

Much like its competitor, the Cummins engine, the Powerstroke offers remarkable power and reliability, making it a popular choice for vehicles such as school buses. Not only does it have a devoted fan base within the Mopar community, but it has also garnered a strong following among Ford enthusiasts. As a result, the intense rivalry between the Powerstroke and 6.7l Cummins diesel shows no signs of weakening.

6.7 Powerstroke Vs. 6.7 Cummins

The Cummins and Powerstroke engines share several key similarities. Firstly, they are both diesel engines and make use of a turbocharger. Additionally, they both boast four valves per cylinder and utilize Bosch components for fuel delivery and management.

While these features may seem relatively standard for diesel engines, the most notable difference between the two is the 6.7l Cummins’s straight-six design compared to the Powerstroke’s V-8. It appears that both Ford F-Series and Dodge Ram trucks plan to continue with these distinct configurations in the near future. Despite their differences, both engines perform exceptionally well and offer an impressive amount of power and torque.

5 Major Symptoms of a Failing Head Gasket

It’s not someone’s desire to pay for a burst head gasket, but worse things happen.
One of the most frustrating and expensive situations car owners dread is finding out that their engine needs to be replaced, or worse, has a cracked engine block.
In addition to being a serious issue in and of itself, a burst head gasket can cause your car to suffer from visually stunning damage very rapidly if it is not fixed immediately away.

We’ll go over the five most frequent causes of head gasket problems because we know how frustrating it is for drivers to find out they have a blown head gasket. To avoid this nightmare, it’s important to be proactive and learn more about the components of your engine. A group of factory-trained specialists at Capitol Toyota are capable of handling blown gaskets and other issues with authentic OEM parts.

What Does a Head Gasket Do?

You may not realize it, but your engine is actually made up of two main sections: the cylinder head and the cylinder block. The cylinder head houses essential parts such as valves, spark plugs, and camshaft(s), while the cylinder block contains the cylinders and pistons. A vital piece connecting these two engine components is the head gasket. By understanding the role it plays, you can spot potential issues and prevent costly repairs in the future.

The head gasket plays a critical role in your engine’s functionality, acting as a barrier against potential leaks of coolant and engine oil into the cylinders. In addition, it traps the firing pressure within the cylinders to ensure optimal performance. Its job is no small feat – the head gasket must withstand the immense pressure and movement of two surfaces expanding, contracting, warping, and rubbing against each other, all while keeping the vital substances of coolant and engine oil contained within the engine’s casting ports.

Causes of a Blown Head Gasket

The engine of your automobile runs in harsh, very heated circumstances. Your engine may overheat and blow a head gasket if this heat builds up more than usual. Due to the excessive heat, the engine block and cylinder head experience an overbearing expansion, ultimately leading to the failure of the head gasket. Another reason why head gaskets fail is detonation, which ruins the fire rings or armors and permits cylinder pressure to seep past them.

Signs of a Failing Head Gasket

signs of a Failing Head Gasket

1. Overheating of the Engine

Regarding the engine overheating, you’ll be left wondering which issue arose first. Was the engine overheating due to the head gasket leaking into it, or did the engine’s heat cause the parts to enlarge and eventually leak the head gasket? Operating a car with an overheating engine is a one-way ticket to engine failure, regardless of what causes the issue.

It is recommended that you see the Capitol Toyota service center for a comprehensive diagnostic if you are having this issue. Our skilled crew can swiftly swap out the defective head gasket for an excellent OEM component.

2. The tailpipe emits white smoke

Since coolant is in the main fabricated from water, while it burns in the engine, water vapor can be visible as white smoke coming from the exhaust. This indicates that a head gasket leak is inflicting the engine to devour coolant.

If the engine isn’t the use of coolant and the coolant degree is constantly low, you may want to check for leaks within the cooling device or outdoor the engine, in which the cylinder head and engine block meet.

3. Insufficient Coolant Level

Your engine may start using coolant if the head gasket breaks between a coolant channel and one of the combustion chambers. This can cause the engine to overheat due to an inadequate coolant level. In addition to burning coolant, an engine can exhibit other symptoms.

4. Rough Idle/Engine Knock

If a head gasket is leaking badly, it will partially or totally block combustion gases from escaping through the exhaust system. Compression will be lost due to this. Subsequently, the engine may stall, knock and run roughly when idle.

Shop all only at Tracktech Fasteners

However, the engine could also run rough or knock out due to other reasons. In order to look for a head-gasket leak, our experts may also perform a compression leak test. Two indicators of an internal failure of the head gasket are when combustion gases are mixing with the engine oil.

contaminated Engine Oil

5. Contaminated Engine Oil

It’s common knowledge that oil and water don’t mix, but your engine’s oil will be less slippery if coolant is allowed to invade. If you think your car’s head gasket might be leaking, you could investigate by unscrewing the engine oil filler cap and examining underneath.

This is due to the possibility of engine coolant and oil systems mixing due to a head gasket leak, which might lead to damage.This thick, foamy liquid can collect there. In the event that a pale, frothy oil buildup has accumulated there, the engine oil is probably tainted by coolant.

Head Bolts vs. Head Studs

Understanding the Basics

Thе choicе of hеad bolts or hеad studs for an еnginе in a car can havе a significant impact on how thе vеhiclе opеratеs. Evеn though thеy arе both fastеnеrs and sееm to havе similar purposеs, studs and bolts diffеr from еach othеr in a fеw kеy ways.

What is a Head Stud?

Although a head stud and a hеad bolt arе both composеd of two piеcеs, a stud diffеrs significantly from a hеad bolt in a fеw important ways. Onе еnd of a stud fеaturеs an undеrcut shouldеr that aids in maintaining its stability whilе in usе.

Morеovеr, it lacks thrеads throughout its body, making it possiblе to tightеn it morе prеcisеly than a convеntional bolt. Rathеr, thе parts that thе stud is joining togеthеr arе fastеnеd with nuts. Additionally, studs can bе madе in ordеr to suit particular purposеs.

What is Head Bolt?

A hеad bolt is a cylindrical rod with thrеads that is usеd to sеcurе two parts togеthеr. It is madе up of two componеnts that fit into matching holеs in еach componеnt: thе hеad and thе shank.

Hexagonal hеadеd hеad bolts with slightly tapеrеd shanks arе thе most popular form of hеad bolt. Whеn nеcеssary, this makеs fitting and rеmoving еasiеr. Dеpеnding on thе purposе for which thеy arе dеsignеd, hеad bolts arе availablе in various diamеtеrs and lеngths.

Which One Should I Use?

What is thе Diffеrеncе bеtwееn hеad studs and hеad bolts? For startеrs, studs arе normally thrеadеd on both еnds and frеquеntly contain an unthrеadеd arеa in thе middlе of thе shaft, whеrеas bolts arе usually partially or fully thrеadеd. Furthеrmorе, bolts always havе a hеad, whеrеas studs don’t.

It is usеful to kееp sеvеral things in mind whilе wеighing thе advantagеs of head studs and bolts. A fеw important considеrations arе torquе prеssurе, gaskеt alignmеnt, ovеrall еnginе pеrformancе, and еasе of assеmbly and rеmoval.

Thе kind of hеad fastеnеr that is utilizеd is frеquеntly dеtеrminеd by thе еnginе’s powеr and accеlеration capability. For instancе, thе еnginе fastеnеr nееds of a high-еnd or racing modеl car will diffеr significantly from thosе of an еvеryday car.


Head Bolts

Installing hеad bolts is simplеr than installing studs, which is onе of thеir advantagеs. Furthеrmorе, hеad bolts that arе in good condition can bе rеusеd, but brokеn studs nееd to bе rеplacеd. Additionally, hеad bolts arе typically lеss еxpеnsivе than studs.

Head Studs

Thе morе stablе connеction that studs offеr bеtwееn thе еnginе block and thе cylindеr hеad is onе of thеir bеnеfits. Furthеrmorе, studs arе lеss pronе to brеak than hеad bolts, which could sеriously harm an еnginе. Additionally, studs еnablе morе prеcisе torquеing, which rеducеs thе likеlihood of lеaks.

Engine Head Assembly

Onе of thе primary distinctions bеtwееn hеad bolts and hеad studs is how an еnginе is assеmblеd or rеpairеd. Highеr-еnd hеad studs with nеar-pеrfеct alignmеnt can bе usеd to sеcurеly position thе hеad gaskеt and cylindеrs thanks to thеir prеcisе dеsign and manufacturing tolеrancеs. Using hеad studs to construct an еnginе is madе simplеr by this fеaturе.

But whеn it comеs to taking apart a car еnginе or doing maintеnancе likе rеplacing a part, hеad bolts arе far morе practical. Mastеr cylindеrs and othеr parts that еxtеnd into thе еnginе compartmеnt arе common in daily-usе automobilеs. In accordancе with thеsе critеria, hеad bolts rеplacе hеad studs by еnabling thе rеmoval of thе cylindеrs without rеquiring thе rеmoval of thе еntirе еnginе from thе vеhiclе.

Statеd diffеrеntly, hеad bolts arе morе appropriatе for daily, pеrsonal cars, but hеad studs arе bеttеr suitеd for high-pеrformancе vеhiclеs rеquiring morе powеr. Thеrеforе, it would bе incorrеct to say that onе kind of fastеnеr is inhеrеntly bеttеr than anothеr. Instеad, thе choicе is contingеnt upon thе typе of car in quеstion and its intеndеd usagе.

Torque Efficiency

Torquing a bolt into place is a necessary step in engine assembly or maintenance. The head bolt must be rotated into its slot in order to engage the threads and lock it into place because of the way it is designed.

Because of the twisting and vertical clamping forces produced by this action, the bolt will stretch and twist as the load builds up inside the engine’s combustion chamber. The bolt’s ability to retain the head is significantly diminished and it creates a less dependable seal in high-powered engines because it must simultaneously respond to two stresses.

On the other hand, no clamping force is applied directly while tightening a head stud into position. Up to “finger tightness,” or the point at which it would be tightened by hand, a stud can be threaded into a slot. The cylinder head is then inserted, and the nut is torqued against the stud to secure it.

Rather than the fastener’s own torque, the nut torque produces the clamping force, completely avoiding the rotational force. The stud will only expand along the vertical axis under the pressure of the nut because it is torqued from a relaxed state and will not rotate at the same time.


Depending on the intended use, both head bolts and studs have advantages and disadvantages. Knowing what each one has to offer will enable you to choose the one that will best suit your requirements and help you finish the project on time! Knowing the distinctions between a head bolt and a stud can help you guarantee that your project will be completed correctly each and every time!

Which Head Studs are the Best for Use?

A common misconcеption rеgarding fastеnеrs is that incrеasing torquе rеducеs thе likеlihood of joint sеparation, or lifting a cylindеr hеad. Thе bеliеf that “biggеr is bеttеr” still prеvails among many companiеs bеcausе thеir fastеnеrs can rеach morе torquе than othеrs, which will incrеasе еnginе safеty. Although this isn’t totally untruе, it also doеsn’t providе a strong casе for thе fastеnеr you’rе using.

Wе kееp wondеring which hеad studs should I usе? Modеrning thе hеad studs on your еnginе is еssеntial to improving longеvity, dеpеndability, and pеrformancе. Gеtting thе corrеct hеad studs is еssеntial to prеsеrving thе structural intеgrity of your еnginе, whеthеr you’rе into high-pеrformancе racing, hauling, or daily driving.

What arе Hеad Studs?

Hеad studs, which arе frеquеntly utilizеd, arе significantly infеrior to hеad studs. Thеy arе prеfеrrеd by ownеrs of Powеrstrokе, Cummins, and Duramax diеsеl еnginеs bеcausе thеy can sustain significantly grеatеr prеssurе than hеad bolts.

Thе Basics of Hеad Studs

Thе thrеadеd fastеnеrs known as hеad studs sеrvе to sеcurе thе еnginе block and cylindеr hеad togеthеr. Studs arе lеss likеly to strеtch, producе a morе constant clamping forcе, and arе morе rеsiliеnt to thе harsh circumstancеs that arе frеquеntly sееn in high-pеrformancе systеms than hеad bolts.

Factors to Considеr

1. Matеrial Mattеrs

Hеad studs arе madе of a variеty of matеrials, еach with spеcial qualitiеs.

ARP2000: Thе strеngth and dеpеndability of this alloy arе wеll-balancеd.

L19: Distinguishеd by its еlеvatеd tеnsilе strеngth, L19 finds applicability in harsh еnvironmеnts.

Titanium: Excеllеnt for rеducing wеight, but somе durability may bе lost.

2. Strеngth in Numbеrs

Tеnsilе strеngth is an important considеration. It gaugеs how rеsistant a substancе is to bеing pullеd apart by forcе. Bеttеr pеrformancе undеr strеss is typically indicatеd by a highеr tеnsilе strеngth. Considеr thе uniquе rеquirеmеnts of your еnginе whilе sеlеcting hеad studs.

3. Thrеad Talk

Considеr thе sort of thrеad. Comparеd to cut thrеads, rollеd thrеads arе oftеn strongеr and morе fatiguе-rеsistant.

4. A Layеr of Protеction

Think about applying coatings to prеvеnt corrosion. Your hеad studs’ lifеspan can bе incrеasеd by zinc or black oxidе plating, particularly undеr a variеty of working еnvironmеnts.

5. Application Awarеnеss

Important considеrations includе thе еnginе typе and its intеndеd usе. Diffеrеnt hеad studs may bе rеquirеd for a high-pеrformancе racing еnginе than for a daily drivеr or towing rig.

Notablе Brands

High-quality skull studs arе thе spеcialty of sеvеral rеspеctеd manufacturеrs. Think about choicеs from:

ARP: Known for manufacturing fastеnеrs with еxcеptional pеrformancе.

TrackTеch Fasteners: rеnownеd for its dеdication to producing sturdy and dеpеndablе fastеnеrs.

Stud Boy: Providеs a rangе of hеad studs suitablе for various usеs.

Installation Tips

Thе sеlеction of hеad studs is not as crucial as corrеct installation. Usе thе appropriatе lubricants, pay closе attеntion to thе manufacturеr’s instructions, and makе surе thе torquе spеcifications arе followеd whеn installing thе product.

Rеalizing thе Bеnеfits

Invеsting in supеrior hеad studs can makе a big diffеrеncе in your еnginе’s longеvity and pеrformancе. Bеttеr hеad gaskеt sеaling, a lowеr chancе of hеad lift, and incrеasеd stability undеr hеavy loads arе somе of thе advantagеs.

Consult with Expеrts

It can bе difficult to sеlеct thе idеal hеad studs bеcausе thеrе arе so many options. Always sееk thе counsеl of knowlеdgеablе еxpеrts or еnginе buildеrs who can offеr customizеd guidancе basеd on thе particular rеquirеmеnts of your еnginе.

Do Wе Nееd Hеad Studs?

All automobilе еnginеs, particularly hеavy-duty diеsеl еnginеs likе Powеrstrokе, Cummins, and Duramax, undеrgo pеriodic strеss of somе kind. Hеad bolts or hеad studs arе what kееp thеsе еnginеs from collapsing, blowing thе hеad gaskеt, or еxpеriеncing othеr similar issuеs. Both ownеrs of bullеtproof trucks and pеrformancе-focusеd diеsеls highly rеcommеnd hеad studs.

Should I Rebuild Or Replace My Blown Diesel Engine

Whether or not to rebuild and repair or replace a diesel engine is a very common discussion in the diesel community. Many Powerstroke, Duramax, Cummins, and other diesel truck owners want to keep their trucks even after catastrophic engine failures which leads to the decision of whether to repair the engine or rebuild the engine. We’ve been around diesel engines for decades, and we might know a thing or two about them, so we’ll help you decide.

Here is what you’ll need to consider.

What Do I Need To Rebuild a Diesel Engine?

You cannot rebuild an engine without adequate tools, knowledge, and skills. And even though there are wizard diesel DIY mechanics out there, there’s still a lot more to rebuilding a blown diesel engine.

The first thing you’d want to consider is if you have the right tools for the job. There are many different unique tools manufacturers use to build engines and tools that those who specialize in rebuilding engines use. Unless you’re one or the other you most likely don’t have these tools. These are very specific measuring tools used to measure clearance, true level, and similar. You could use plastic gauges or spirit levels as alternatives, but that can easily lead to improper measurements.

For example, even the slightest mistake in measuring clearance can lead to poor clearance which can lead to loss of oil pressure, and once you lose oil pressure it’s back to square one with the rebuild. – Even if you successfully rebuild an engine this way, it’s probably not going to last longer than a few months, and at TrackTech, we just don’t believe in that; we believe in quality, perfection, and durability.

Let’s say that you either have all the necessary tools or you’re ready to buy them. Now it’s a matter of what condition is your engine in, is it even worth rebuilding the diesel? Of course, there are engine rebuild kits that will help you replace all the parts that commonly wear out, but what about machine-ing?

For example, over time the piston rings wear out the bore of the cylinder, making it wider. To properly rebuild an engine, you’d have to take the engine to a machine shop so they can return the cylinders to their true bore, find larger pistons, or find another solution, and the rabbit hole continues.

Lastly, you wouldn’t want an inexperienced heart surgeon performing heart surgery on you. Diesel engines are more than complex, so if you don’t have the experience and the knowledge, you could easily torque a few bolts improperly, miss a few measurements, etc. and once again, if that happens, it’s back to square one. And even if you are the most detail-oriented mechanic on earth, you still don’t have any insurance that the engine will last.

When Should I Rebuild a Diesel Engine?

Replacing a blown diesel engine is usually the more cost-effective option. However, there are still scenarios when it might be a better idea, and a more cost-effective one, to rebuild a blown diesel engine.

There are a few engines out there that are highly desirable and therefore more expensive. Many of these engines aren’t even in production any longer, which further drives their value up. If you do have one of these engines under the hood of your diesel truck, rebuilding it wouldn’t be that bad of an idea. Of course, as long as you’re knowledgeable, skillful, and possess the necessary tools to rebuild or repair a diesel engine.

Another case scenario when you might want to rebuild a diesel engine is if you have a lot invested into it. High-performance diesel engines are hard to come by, and simply scrapping your modified engine for its stock counterpart doesn’t sound very appealing. Rebuilding and repairing it properly is definitely the better option.

Those are unique scenarios that not everyone can relate to, so what should you do if you’ve decided that rebuilding an engine isn’t worth the time, effort, and money?

The Best Diesel Engine Replacement

There are a few valid options for a diesel engine replacement; a salvaged engine; a manufactured short block or a manufactured long block.

Salvage yard engine is essentially a Schrodinger’s cat, you might find a perfectly healthy engine, or you might find one that’s going to die within a year. After all, many people have had access to salvage yard engines, and they could’ve taken a few key parts, thrown something into the engine, or similar. This is the most cost-effective option, and if you’re feeling lucky it could turn out pretty well, but you have to be willing to gamble.

A manufactured long block is the engine block and cylinder head with the bottom and the top block already pretty much assembled. The only thing that you’ll have to do is move over a few parts from your old engine to the new one and it’s ready to go. This is the most expensive, and the middle-of-the-road option because not every part is going to be of the highest quality, so it might not last as long as you’d like it to.

Read about: Considerations when modifying your diesel truck

The best possible replacement option, as long as you know how to properly torque down a few studs, is a short block. A short block is the engine block itself with the bottom end assembly. You would just need the cylinder head and everything that goes with it. This is, in our opinion, the best option because it allows you to customize your engine either for performance, toughness, reliability, and/or longevity.

Instead of head bolts that usually come with an engine or a long block, you have the chance to make your new engine bulletproof by installing head studs. Aftermarket head studs are one of the best possible engine modifications you could do for performance, reliability, and durability.

Whether you opt for a long block or a short block, take a good look at the manufacturer’s warranty. How long are they willing to cover their engines, what happens if the long or the short block you bought blows up during that time, and if you’re the one who’s going to be paying for the repairs/replacement.

Should I Install Head Studs In A Diesel Engine?

Head studs are an excellent performance-supporting, reliability, and durability modification for every engine. They’re beloved by owners of diesel trucks in particular because diesel motors sustain much more pressure every day than gasoline engines.

Aftermarket head studs are responsible for keeping the engine together, in one piece without any static parts moving, and properly sealing the engine block, the head gasket, and the cylinder head.

For example, the 6.0 Powerstroke or the 6.4 Powerstroke are known to be unreliable, but as soon as they’re “studded” they essentially become bulletproof. So, installing head studs in your brand new engine, or during the rebuild of your old engine, will ensure that you never blow that motor. Here are 6 benefits of aftermarket head studs if you’d like to learn more about them.

TrackTech’s goal is to create head studs and other fasteners, of the highest quality. We’ve roamed the earth in search of the strongest alloys, and once we found them, we created head studs that can withstand up to 240,000 psi worth of pressure. In comparison, regular head bolts can sustain up to 160,000 psi, while regular head studs can sustain about 200,000 worth of psi. If your goal is to make an engine that can never fall apart, take a look at our Powerstroke, Duramax, and Cummins parts

How To Prevent Your Diesel Motor From Blowing Again?

There are quite a few things that could prevent a blown diesel motor, and make it last even up to 1 million miles. If you’ve just bought, or hand-built, a new engine, this is what’ll make it indestructible.

Since diesel engines are more complex and delicate than their gasoline counterparts, they need more care. A regular maintenance schedule will help a diesel engine operate optimally, as well as make it much more reliable. Monitors and controllers are perfect for noticing issues before they even occur and nipping the problem in the bud. Those are just some of the examples of how to care for your diesel engine. Here’s a thorough explanation of what’ll make your diesel engine run smoothly, and reliable, for a long time.

The End Of The Road

Even for the most experienced mechanics, taking a motor out of the engine bay can take hours. Taking an engine apart, finding all of the issues, and properly putting everything back together can take months, especially if you have other responsibilities. In some cases, this is a valid option, but a short block manufactured by the experts who make a living from creating them and then modifying the rest of the engine the way you want to is, hands down, the best way to make a powerful and an indestructible engine.

Head studs, being the best modification for making an engine bulletproof, are basically essential for either a brand new or a rebuilt engine.

5 Things to Know Before Purchasing a Chevy Duramax Silverado

The Chevy Silverado is one of the most popular full-size pickup trucks made in America. The model comes in various trim levels with a variety of options. One option you may want to consider is a Chevrolet Silverado  Duramax to take advantage of the benefits of a diesel engine.

If you’re thinking of buying a Chevy Duramax as your next diesel truck, here are five things you should know.

1. The Silverado with Duramax Uses an Automatic Transmission

When you look at the 2021 Chevrolet Silverado options, you’ll note that the configurations with the 3.0L Duramax Turbo-Diesel I6 engine all come with 10-speed automatic transmissions. This is important to be aware of, as some drivers may have a specific preference for a manual transmission. This, unfortunately, won’t be an option.

However, if you’re happy with an automatic transmission in your diesel truck, you’ll be satisfied with this option.

2.  You Have Three Bed and Cab Configurations to Choose From

The 2021 Chevrolet Silverado has three configurations with a Duramax diesel engine:

  • Double Cab / Standard Bed
  • Crew Cab / Standard Bed
  • Crew Cab / Short Bed

Read about: The difference between Duramax vs Powerstroke vs Cummins

You’ll want to consider how much passenger space you need and how much bed space you want. It must be noted here that if you’re looking for a regular cab and long bed, your only options are gas-powered engines.

3.  Fuel Economy

Diesel engines tend to get higher fuel economy due to the way the fuel combusts. While gasoline is a light fuel that must be mixed with air and ignited with a spark, diesel is heavier and can be ignited through compression alone.

The Chevy Duramax Silverado is no exception. While the fuel mileage will vary depending on which specific configuration you choose, the 2WD with Duramax gets an estimated 23 MPG highway and 33 MPG in the city.

4. Great Range

The Duramax diesel engine gets a lot of miles between refills. On a full tank, you can expect to get up to 682 miles of fuel range for highway travel. For perspective, this means you could drive from Los Angeles to San Francisco (633 miles) on a single tank of diesel.

Aside from the size of the tank and the general fuel efficiency of diesel, the Duramax has precision fuel metering and improved exhaust tuning, which help the engine operate more efficiently.

5. The Duramax Design

The Chevy Duramax engine is a result of precision engineering and a focus on performance. The well-balanced inline-six-cylinder design and the hypereutectic aluminum pistons allow for smooth operation. In short, this thing performs well because a lot of thought was put into developing the best 3.0L diesel engine possible.

While the Duramax is well-engineered, there are always tweaks you could do to make it even better. For example, high-quality aftermarket head studs are a great upgrade over the factory head bolts. TrackTech offers a variety of racing fasteners and head studs, including a good selection for the Chevy Duramax.

The Chevy With a Duramax Engine is a Sound Investment

The Silverado is Chevy’s most popular pickup truck for good reason. It offers a great everyday driving experience, while still having plenty of hauling, towing, and passenger capacity. Paring the Silverado with the Chevy Duramax diesel engine will allow you to take advantage of superior performance, efficiency, and fuel economy.

5 Things to Know Before Purchasing a Dodge Ram with Cummins Engine

The Cummins diesel engine has been around since the late 80s, offering a powerful and efficient diesel engine to Dodge Ram pickup trucks. Whether you’re looking at an older model Dodge Ram or a newer Ram, buying a model with a Cummins diesel is well worth considering.

Here are a few things you’ll want to be aware of before making a purchasing decision.

1. Pure Towing Power

One of the primary draws of diesel engines is the torque produced for towing applications. If this is a crucial consideration for you, you’ll want to focus on models no older than 2013.

Read about: Considerations when modifying your diesel truck

Why is this important? In 2013, the Cummins Ram was able to achieve 850lb-ft torque for the first time. This was a giant leap in torque and hence a major step up in the line’s ability for heavy-duty towing. If you want even more towing power, you’ll want a 2019 or new model for 1000lb-ft of torque.

2. Fuel Economy

Buying a newer vehicle will of course help with fuel economy with all vehicles. Diesel engines are also known to generally be more fuel-efficient than their gas-powered counterparts. This is one of the big selling points for diesel engines. Because diesel can be ignited through only compression rather than relying on sparking a fuel-air mixture, the diesel engine is more efficient.

With that said, if you want the best fuel economy possible, the newer Ram 2500 you buy the better. The 2022 Ram 2500 offers a gas-powered option as well, but diesel engines generally get about 20-35% better mileage than gas.

3. Consider Truck Size

Only the Ram 2500 includes the Cummins diesel engine option. If you’re in the market for a heavy-duty workhorse of a truck, then this is a great choice. However, maybe you’re wondering if you need that much truck?

Read about: Why Choose TrackTech Fasteners?

Frankly, if you do a lot of heavy towing, plow snow, or perform other activities that really make your truck work, then the Ram 2500 with the Cummins is the best option. For lighter duty usage, the Ram 1500 would be the better choice. The Ram 1500 does not offer an option for a Cummins diesel engine, but it does have a smaller 3.0L diesel option in the newest models.

4. Cummins Turbo Diesel Provides Plenty of Horsepower

In general, gas-powered engines tend to provide more horsepower than diesel engines. This is because gas burns much quicker than diesel allowing the engine to rev faster.

With that said, the 6.7L Cummins Turbo Diesel can definitely hold its own. The latest model reaches 400 HP to go along with its 1000lb-ft torque, which means it has plenty of power and acceleration.

5. Aftermarket Parts Availability

Aftermarket upgrades to your diesel truck can provide a nice performance and reliability boost. This is true whether you’re looking at a brand new 2022 Ram 2500 or a used 2013 Dodge Ram 2500.

There are a wide variety of aftermarket parts available for Cummins-powered Ram trucks of all years.  From exhaust upgrades to intake manifolds, there are some great options. One of the simplest and possibly the most critical is the option to replace the OEM head bolts with aftermarket head studs.

TrackTech makes great aftermarket racing fasteners and general diesel head fasteners for a variety of engines. Fortunately, this includes a wide range of head studs for the Cummins diesel engines. These high-quality head studs will ensure your diesel engine isn’t held back due to weak fasteners.

Final Verdict: The Cummins Ram 2500 is a Powerhouse

The Dodge Ram–and now simply the Ram–is a great overall lineup of trucks. The Ram 2500 line is one of the most respected heavy-duty vehicles on the market today. If you’re considering buying one of these vehicles, you’ll be getting a vehicle that is powerful and will also edge out similar gas engines due to the Cummins Turbo Diesel.

Overall, if a heavy-duty workhorse is what you need, you won’t be disappointed in a Cummins-powered Ram 2500.
