A cylinder head gasket is a crucial sealing component located between the engine block and the cylinder head in an internal combustion engine. Its main functions are: Sealing the combustion chamber to maintain compression and ensure efficient engine performance. Preventing leakage of coolant and engine oil between the block and head. Withstanding high pressure and temperature, as it operates in one of the most extreme environments in the engine. If the head gasket fails (commonly called a blown head gasket), it can cause symptoms such as overheating, loss of power, white smoke from the exhaust, oil–coolant mixing, and engine misfires.
