Good To Know

Q: Does this gasket need sealant to install? A: A dry install is normally sufficient since the gasket is molded to the OEM profile, but a thin film of suitable sealant can be added at corners if your service manual calls for it.

Q: How often should a valve cover gasket be replaced? A: Replace it any time the valve cover is removed or when oil seepage appears at the joint, since reusing a compressed gasket often leads to leaks.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
