What is a valve cover gasket?

The valve cover sits atop the cylinder head, and the valve cover gasket is sandwiched between them to keep circulating oil inside. The majority of valve cover gaskets are molded rubber, tailored to fit. In some cases, the spark plug tube gaskets are part of the valve cover gasket, and are replaced at the same time. Valve cover gaskets are different than head gaskets.

Can I drive with a valve cover gasket problem?

A vehicle can still be driven with a leaking valve cover, but the leaking oil will cause other problems over time. Spark plug wells can fill with oil, causing a misfire. Oil dripping on coolant hoses will cause them to become soft and eventually burst. And the smell of burning oil will become more noticeable in the cabin.

How often do valve cover gaskets need to be replaced?

Repair intervals vary greatly by vehicle and driving conditions. The valve cover gasket does not wear like a tire or a ball joint, but eventually the gasket's rubber or cork will degrade to the point where it leaks.

How are valve cover gasket issues diagnosed?

It is easiest to spot oil leaks when they are new or fresh. The technician may clean the fluid around the leak and direct you to come back later to confirm where the leak is coming from.
