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.

Frequently Asked Questions

Is a blown head gasket worth fixing?
Depends on the car's value. If the repair costs more than half the car's worth, consider a used engine or selling as-is.
