What It Is

The head gasket seals the engine block to the cylinder head, keeping oil, coolant, and combustion gases in their proper places.

Why It Matters

A blown head gasket can lead to a warped head, hydrolocked engine, or complete engine failure. The fix is labor-intensive but often cheaper than a new engine.
