Is It Worth Fixing A Blown Head Gasket

Can A Blown Head Gasket Be Repaired Or Does The Engine Need To Be Replaced?

If you're wondering, “is it worth fixing a blown head gasket?” The short answer is it depends. If fixing the blown head gasket will cost you close to 75% or more of your vehicle's value, then it's definitely not worth fixing the vehicle. But, if your vehicle's value is much more than the price if they had the gaskets, you are definitely recommended to fix it.

A head gasket is placed between the cylinders and the other parts in the engine’s compartment. The head gaskets maintain the right pressure level so your engine can produce the right amount of energy at the right time. It also prevents any fluid leaks the cylinders, which results in many negative consequences.

Auto Repairs Are EXPENSIVE

Since the consequences of blown head gaskets are extremely severe, drivers are still required to replace the head gaskets when it blows out.

Head gasket replacement cost is very expensive, and there are plenty of people who are still wondering, “is it worth fixing a blown head gasket?”. So let's take a closer look at the answer in this article and learn more about the negative consequences of blown head gaskets.

What is the head gaskets and what happens when it blows out?

The head gasket is a thin metal layer sitting between the cylinders and the engine compartment. This small thin layer plays an important role and preventing engine damages and maintaining the rights combustion process.

Here are some of the main roles of the head gaskets in your vehicle:

1-    Protect the engine

The head gasket is connected to these cylinders to prevent any harmful gases from leaving the cylinders and therefore damaging the engine compartment. It also prevents any fluids leaks inside the cylinders like the coolant or oil. If any of these fluids made their way to the cylinders, it impacts the overall combustion process and results in many different problems.

2-    Maintain cylinders pressure

Since the head gaskets seal the cylinders completely, it keeps the right pressure level to generate the proper combustion process. Without the right level of pressure, the combustion process will not happen properly, and therefore, will engine will not provide the right amount of power no matter how much fuel you send.

You've probably heard the term “a blown head gasket,” which is the worst thing any driver wants to deal with. This is because the head gaskets are continuously exposed to extreme temperatures inside the cylinders. Therefore, the head gasket can blow out and gets cracked overtime reviews. Many terrible outcomes and consequences immediately occur when that happens, impacting the vehicle's health and energy production.

What are the side effects of a blown head gasket? Does a blown head gasket ruin the engine?

Before we highlight whether it's worth fixing a blown head gasket or not, it is important to step back and understand the negative consequences that could happen when your vehicle's head gasket blows out.

Here are some of the things that will happen and you will notice once the head gasket blows out:

1-    Engine damage is due to overheating

When the head gasket blows out, the ceiling covering the cylinders is gone, and therefore, hot gases escape from cylinders towards the different engine parts. Thus, the engine temperature will increase significantly, resulting in engine overheating, ruining the entire engine, and cause self-destruction.

Also, when the head gasket cracks, it allows the coolant to escape inside the cylinders. Therefore, the coolant will not do its job of reducing the engine temperature when it overheats.

Similarly, the other component that helps reduce the engine temperature is the oil might also escape inside the cylinders resulting in a higher potential for engine overheating and, therefore, engine damages.

2-    Significant reduction and vehicles power

After the head gasket blows out, the air-fuel ratio inside the cylinders can get affected. Also, the combustion process requires a certain level of pressure to continue properly, and when the head gasket is gone, there is no such thing to contain the pressure and help maintain the good combustion process.

3-    Contaminated oil

The oil and coolant run around the engine continuously. The oil is responsible for lubricating the internal moving components and preventing overheating, while the coolant is responsible for reducing the engine temperature every time it exceeds a certain threshold.

When the head gasket blows out, it impacts the pathways of both the oil and coolant. Therefore, the coolant and oil can get mixed, which means that none of them will maintain their right to do their job. Thus, you'll notice that the oil will get contaminated with coolant, and it will see this clearly if you look around the oil reservoir and see a Milky substance floating on the top.

4-    White exhaust smoke

Also, as the coolant gets inside the cylinder, there is a very high chance for this coolant to get burnt, and when the coolant burns out, it generates very thick white smoke, and you'll notice it coming out of the exhaust tailpipe.

Keep in mind that big smoke must be thick and white to confirm that the problem is coming from coolant burning inside the cylinders. This is because there are some chances for white smoke when you get your vehicle started at a cold engine, and it's important not to confuse with both situations.

5-    Leaking fluids

Finally, another common consequence of a blown head gasket is fluids leaking outside of the vehicle. Every fluid must be maintained at a certain level in the vehicle to do its job properly. When the head gasket blows out, it impacts pathways and creates many holes, then cracks in these pathways forcing the fluids to leak outside the vehicle.

You'll see, for example, some puddles of either engine oil or coolant sitting under the vehicle if you load it idle for some time.

If you notice any of the mentioned consequences of blown head gaskets, you must take immediate action. In some scenarios, you are required to pull over and stop your vehicle as soon as possible to prevent ruining the engine and causing major internal problems.

Keep in mind that no matter how high the price of the head gasket, it's never close to the price of the engine, and therefore, if you think that it's worth fixing a blown head gasket, it might not be worth replacing the entire engine if you waited for an extended time frame on the problem.
