Blown Head Gasket Symptoms

While it is true that certain types of car are notorious for blowing head gaskets, the truth is, all vehicles can blow a head gasket at some point.

Blown Head Gasket Symptoms

Whether you drive a vehicle that is infamous for blown head gaskets, or your car has no such reputation, it’s important that you are aware of the signs that indicate that this problem exists.

What Does the Head Gasket Do?

In order to better understand the signs of a blown head gasket, it’s first important to understand what it a head gasket does.

The head gasket creates a seal between two of the most important components of a vehicle’s engine: the engine block and the cylinder head.

It creates a seal for the combustion chamber, as well as the oil and coolant lines that run through the engine. As such, the head gasket must seal exceptionally hot and high pressure gasses that are created as a result of combustion.

It also has to seal coolant, which can range in temperature from cool to the temperature of your engine when in full flow. Because of the widely varying temperatures, the high pressure, and the large surface area, it isn’t uncommon for head gaskets to leak over time.


Diagnosing a Blown Head Gasket

Because the job of the head gasket is to seal off the coolant passages from the combustion chamber, not much of can be seen because it is located deep within the engine.

As sa result, in order to really get a good visual of the head gasket, you would have to take apart a good bit of the engine, which requires a great deal of knowledge and the right tools; and even with both, it can be a very time-consuming and costly process.

Therefore, simply popping the hood of your car and looking at the head gasket probably won’t reveal whether or not a leak exists.

That being the case, it’s very important that you are aware of other signs that can indicate that your head gasket has blown.

There are several symptoms to look out for to help diagnose an issue with your vehicle’s head gasket. Some of the most common signs include:

  • White smoke – If your head gasket is blown, there’s a good chance that you will notice white smoke pouring out of your vehicle’s tailpipe. This is especially true if the leak in the head gasket is internal, which causes coolant to drip and burn during the combustion process.
  • Overheated engine – If a head gasket has blown, the engine will likely overheat. This is especially true if the vehicle is being driven for a long period of time. This occurs because there isn’t enough coolant in the engine, which means that there is too much heat in your engine from the combustion process.
  • Radiator bubbles – If a head gasket is blown, the coolant in the radiator can look as if it is bubbling. These bubbles are gasses that have been created from exhaust, and they push their way into the cooling system during the process of combustion.
  • Misfiring spark plugs -When coolant burns within the combustion chamber, it leaves behind deposit on the spark plugs. These deposits can cause your spark plugs to misfire, which is something that will need treating.
  • Whitish oil – When there is a crack in the head gasket, coolant will leak into the combustion chamber, and make its way into the oil. As the oil and water from the coolant mix, the oil will become whitish in color.

If you find any of these blown head gasket symptoms you should not drive your car.


Repairing a Blown Head Gasket
