Specs At A Glance

Good To Know

Q: Does this gasket need sealant to install? A: Most valve cover gaskets of this type install clean, though some technicians add a small amount of sealant at the corners for extra security. Follow your service manual's recommendation for the 1503 engine.

Q: How do I know if my valve cover gasket needs replacing? A: Common signs include oil residue around the valve cover edges, a burning oil smell, or visible drips after the engine sits. Replacing the gasket when the cover is off for other service saves a second teardown later.

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