Gasket
Gaskets seal the joints between engine parts, and when one fails you may see oil or coolant leaks, smoke, or overheating. A mechanic finds the leaking gasket and replaces it to restore a tight seal and keep your engine protected. Handling it early prevents bigger, costlier repairs down the road.

Frequently asked questions
How do I know which gasket is leaking?
Your mechanic inspects the engine and traces the leak to its source, whether it's a valve cover, oil pan, intake, or head gasket. The color and location of the leak help identify it.
Is a leaking gasket serious?
It depends on which one. A minor valve cover leak is low risk, but a head gasket failure can lead to overheating and serious engine damage, so it's worth diagnosing promptly.
Can a gasket leak be repaired without major work?
Many gaskets, like valve cover or oil pan gaskets, are straightforward to replace. Others, such as head gaskets, require more labor. Your mechanic can explain the scope after inspection.
