Good To Know

Q: Does this gasket need sealant during installation? A: Most valve cover gaskets seat dry on a clean, flat surface, so follow the service manual for your 1503 engine before adding any sealer.

Q: How do I know the gasket needs replacing? A: Oil weeping around the valve cover edge, a visible flattened gasket, or a gasket that has hardened with age are the usual signs it is time for a new one.

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