A head gasket is a gasket that sits between the engine block and cylinder head(s) in an internal combustion engine.
Its purpose is to seal the cylinders to ensure maximum compression and avoid leakage of coolant or engine oil into the cylinders; as such, it is the most critical sealing application in any engine, and, as part of the combustion chamber, it shares the same strength requirements as other combustion chamber components.

Famous quotes containing the word head:
“He was thoughtful and grave—but the orders he gave
Were enough to bewilder a crew.
When he cried “Steer to starboard, but keep her head larboard!”
What on earth was the helmsman to do?”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
