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:
“A man of sense and energy, the late head of the Farm School in Boston Harbor, said to me, “I want none of your good boys,Mgive me the bad ones.” And this is the reason, I suppose, why, as soon as the children are good, the mothers are scared, and think they are going to die.”
—Ralph Waldo Emerson (1803–1882)
