A head gasket is like a critical seal, located between your engine's block and the cylinder head. It is made out of machined casting in the internal combustion engine, with holes to hold the pistons.

What is its function? Like mentioned, the head gasket is a seal, preventing leakage to both engine block and cylinder head. It does this through compression.

The head gasket has a compression ratio that prevents your car's liquids (water, oil, exhaust gas, or fuel) from coming into the wrong areas of the engine, as well as separating both water and oil that pass through them.
