Can Head Gasket Cause Misfire? (All You Need to Know)

A Head gasket is a crucial part of a vehicle. It ensures the security of a cylinder. Mainly, the head gasket is used to seal the combustion gas firmly into a cylinder. It secures the cylinder from not getting any oil leakage from the gasoline pipe or the engine leaks.

A bad head gasket is always a risk for the cylinder. You have to check it regularly and make sure it seals the cylinder perfectly. Moreover, the gasket, if it goes wrong, will create issues for both the engine and cylinder.

Can head gasket cause misfire?

The head gasket can cause a misfire. But it will secure the cylinder from getting oil from the gasoline pipe and engine. When the head gasket goes wrong and gets damaged, it will fail to protect the cylinder. As a result, it will cause misfires. That’s why you should check the head gasket.

If you check the head gasket, you will know if it goes wrong or gets damaged. In that case, you can securely replace or repair the head gasket instantly. Remember, the faulty or bad head gasket will create more trouble for your engine and cylinder.

That’s why regular checking is essential. Regarding engine and cylinder safety, you can make a routine of cross-checking. And you should check both parts one after another.

It will ultimately help you reduce the risk of having a bad head gasket.

Leaky head gasket:

The leaky head gasket will surely cause a misfire. One of the main reasons is the low compression rate. When the head gasket gets leakages, the compression will lower between the cylinders.

In that case, it will directly affect the engine. You might find that the engine is stalling. That ultimately led to the misfire after a few minutes of driving. So, if you check the engine lights, you must check the head gasket.

Blown head gasket:

Sometimes, the engine blocks and cylinder cap fails, called the blown head gasket. Therefore, the blown head gasket can cause engine misfire.

On the other hand, the blown head gasket is risky for the cylinder and engine. Both parts will start to decline their performances, leading to great concern.

Therefore, when you get the misfires, you should go to the head gasket and replace it if needed.

Bad intake head gasket:

When you see smoke is coming from the exhaust, you have to check the head gasket. It is a sign of a bad intake head gasket most of the time. It will lead to a serious accident.

Also, the bad intake head gasket can cause the engine to misfire. It’s a common symptom. You need to take it seriously and change the bad intake head gasket after that.

Cracked head gasket:

When your engine cannot get enough air and becomes heater than the expected condition, it might blow the head gasket.

At least, it will crack the head gasket. Therefore, the cracked head gasket will cause engine misfires for sure.

Moreover, the cracked head gasket will also lead to cylinder leakages. You will get lower power from the engine and a low coolant level. As a result, the engine will get heated.

5 reason why head gasket cause misfire

There can be many reasons why a head gasket will cause misfires. Check the list below to know about them.

Improper Sealing:

The Head gasket will cause a misfire when it fails to seal the gas combustion firmly. It goes through the coolant part and becomes a mess at that time.

That means both the head gasket and the coolant part get in touch, which in the end, will cause a misfire. That’s the first reason.

Engine Heat:

The second reason is engine heat. When the head gasket fails to seal the cylinder properly and the coolant port gets the gas, the engine will fail to get the cool air or pass the heated air.

Therefore, it will become hot and will misfire. That’s how the head gasket can cause a misfire.

Leakage Issues:

When the head gasket leaks, it will lower the compression rate. And, the lower compression rate will make the engine slower and produce excessive heat.

As a result, the engine will misfire. That’s the third reason why head gaskets cause a misfire.

Bad Engine:

Sometimes the engine goes wrong and stops working like before. At that time, it will reduce the working power too; therefore, it will produce heat, which will cause engine misfires.

Longtime Use:

If you use the same head gasket for a long time, it will lose the materials and become weaker.

Therefore, It will help the cylinder to leak the gas or fuel. As a result, the spark plugs will get oil or gas. That will ultimately cause the engine to misfire.

So, these are the top five reasons why the head gasket causes misfire. But there are more you can count. However, you can solve these issues by following some simple steps or taking them to the professionals.

How do I know if my spark plug has a blown head gasket causing misfires?

You need to check the engine power and the temperature. When your engine produces too much heat, it will be an indication of having a blown head gasket.

Moreover, some more symptoms will also tell you if the spark plugs have a blown head gasket causing a misfire.

When your spark plugs go wrong, it will decrease the engine power and lead to a misfire. In that case, the head gasket will also contribute. Mainly, the spark gets leakage oil for the blown head gasket, which ultimately causes misfires.

Overheating, engine performance, the check engine light, and excessive smoke from the exhaust will tell you if your spark plug has a blown head gasket causing misfires.

Can you fix a head gasket without replacing it for misfires?

You can fix a head gasket without replacing it for misfires. Most times, your head gasket will leak; at that time, you can buy the head gasket fix. It’s spray or adhesive material that will help you repair the lousy head gasket.

On the other hand, replacing the head gasket is always challenging. So, repairing the head gasket will be a good decision for you.

You can search for the head gasket fix; you will find different products that will help you fix a head gasket without replacing it for misfires.

Can head gasket seal stop an engine misfire?

The head gasket seal can stop an engine misfire. But to make it happen, you need to ensure that the head gasket is fine and healthy. Additionally, you need to repair the bad head gasket and ensure the seal is secure.

On the other hand, the head gasket seals the combustion gas inside the cylinder to secure the spark plugs and coolant port. Therefore, your engine will get enough fuel and cool air. That’s how the head gasket seal can stop an engine misfire.

The head gasket seal will also secure the cylinder. It will firmly secure the gas and leak any gas from the cylinder. That will ultimately help to stop the engine misfires.

How to fix the head gasket to stop the misfire?

Fixing the head gasket is not a challenging task. Even you can fix it without having any prior experience. You can follow our simple steps and fix the head gasket properly.

Detach the gasket:

Detach the head gasket first and find out the leaks and damage apart from it. It is the first step to fixing the head gasket. You can follow the user manual guide to detach the head gasket.

Buy fixing glue:

You need to buy the head gasket fix product. You will find it on the local market.

If you don’t see it, search and buy the fixing material online. It’s an adhesive glue-type material that will help you fix the head gasket to stop the misfire.

Clean the gasket and apply fixing glue:

Now. You have both the damaged head gasket and gasket fix material.

You need to clean the head gasket before applying the fixed product. You can simply use any microfiber cloth and clean the head gasket.

Seal the damaged areas:

It’s time to apply the head gasket fix material on the leaks and damaged parts.

You can put the material slowly and let it dry for a long time so that it will create a coat on the leaks that will ultimately fix the damaged head gasket.

These are the steps you should follow to fix a head gasket to stop engine misfires. In the worst situation, you will need to replace the head gasket.

Final Thoughts

The head gasket can cause engine misfire. When the head gasket is blown or has a bad intake, it will cause the engine to misfire. On the other hand, overheating the engine will also damage the head gasket, which will also cause the misfire to take place.
