Good To Know

Q: Does this gasket require sealant during installation? A: Most valve cover gaskets install clean and dry, but always follow the service manual for your specific engine. A thin bead of appropriate sealant may be needed only where the manual specifies.

Q: How do I know if my valve cover gasket needs replacing? A: Common signs include oil residue around the valve cover, visible drips, or a burning oil smell after riding. If you spot any of these, inspect and replace the gasket.

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