Good To Know

Q: Does this gasket require sealant during install? A: Many installs call for a thin bead of appropriate sealant at the cover corners, so check your service manual for the specific procedure.

Q: How do I know when the valve cover gasket needs replacing? A: Common signs include oil weeping around the cover, a hardened or cracked gasket, or a gasket that no longer sits flat during a rebuild.

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