What is a head gasket?

The head gasket is the seal between 2 components of the engine: the head and the block. Its job is to make sure nothing gets in or leaks out.

This is vital to make sure the combustion chamber is perfectly sealed for the fuel ignition process to operate correctly.

Your car engine requires many liquid elements to ensure its correct running. Fuel to power it; oil to lubricate it, and water/coolant to keep it running at its optimum working temperature.

If your head gasket fails, and these fluids are allowed to mix, then it can mean big trouble, and costly repairs.
