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

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.

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.

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.
