Head Gasket Function 

The head gasket is a component that sits between the engine block and the cylinder heads within your car’s internal combustion engine. The purpose of the head gasket is to seal and block off the cylinder entrances. The sealing and head gasket repair fluid ensures maximum compression within the engine mechanism to avoid any excess coolant leakage, leading to overheating, potential fires, and lack of lubrication. 

Head Gasket Anatomy

The cylinder head sits above the cylinder block, helping form the closure on the top of the engine’s combustion chamber. The upper part of the engine is the cylinder head, while the lower part is commonly referred to as the engine block. 

 

The engine block is the lower part of the engine that houses all of the major components of the bottom of your car's motor. This is where combustion occurs in an internal combustion engine and houses important components like the crankshaft.

 

If the crankshaft, housing component, or head gasket fail within the engine, it can lead to irreversible engine failure. As you can see, using head gasket repair fluid is vital to your engine’s lifespan and longevity. 

What is a blown head gasket?

So, here comes our next question – what is the cause of a blown head gasket? The cause could be anything from a coolant leak to internal combustion components concerns. This means that the cause could range in severity from a minor fix to a serious replacement, increasing the overall repair cost. 

 

One of the most confusing aspects of a blown head gasket is the frequency of a blown head gasket resembling another problem in your vehicle. Since head gasket failure could be similar to other issues, drivers may not notice the head gasket leak symptoms before it is too late. 

 

Some examples of common symptoms of a head gasket failure are overheating caused by a blocked radiator, leading to increased engine damage the more you drive. In addition, the coolant in the oil is typically attributed to head gaskets but could be traced back to the intake gasket malfunctioning. 

Blown head gasket symptoms

There are a few key symptoms you can use to determine if your head gasket has become damaged. In this case, you need to use head gasket repair fluid. 

  • External Head Gasket Leak

First, you may have an external head gasket leak. A head gasket leaking can cause coolant to flow for the intake or the exhaust manifold. As this will only happen once your engine is warmed up, you will notice the head gasket leak symptoms by examining the cooling passages or hoses near the head gasket.

  • White Smoke

Second, if you notice white smoke coming from the tailpipe, you may be noticing one of the main head gasket leak symptoms. When the coolant flows into the combustion chamber too frequently, the coolant burns and evaporates with the combustion process. Drivers will notice this smoke differs from moisture you may notice during a cold start, as the smoke will continue even after the engine has been warmed up.

  • Radiator Bubbles

Third, an internal head gasket leak symptom can be noticed by bubbles in the radiator. If the leak causes exhaust gases to leak into the coolant, the bubbles will move into the cooling system during the combustion process, leading to a blown head gasket.

  • Overheating

Fourth, if you have a blown head gasket, your engine will overheat during long drives in tough conditions. This usually happens due to the lack of coolant in your engine, excess heat, and the inability of your car's radiator to cool the engine liquid. If the engine overheats, you will notice one of the main head gasket leak symptoms. 

  • Coolant Leaks

Fifth, coolant leaking into your combustion chamber can move past piston rings and into the engine oil. Over time, oil and water will combine and cause the oil to change color and prevent any lubrication during overheating and engine movement. If your oil ineffectively lubricates your motor, it can cause the need for head gasket fluid.

  • Faulty Spark Plug

Lastly, a broken spark plug or malfunctioning plug can cause tiny white deposits to be left on your spark plugs and engine electrodes. Using head gasket repair fluid can help repair the spark plugs.
