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:
“I ask whether the mere eating of human flesh so very far exceeds in barbarity that custom which only a few years since was practised in enlightened England:Ma convicted traitor, perhaps a man found guilty of honesty, patriotism, and suchlike heinous crimes, had his head lopped off with a huge axe, his bowels dragged out and thrown into a fire; while his body, carved into four quarters, was with his head exposed upon pikes, and permitted to rot and fester among the public haunts of men!”
—Herman Melville (1819–1891)
