Product Description

?

This replacement head cover gasket is specially designed for use on small Honda engines. It is used to provide an air tight seal for the head cover. Over time gaskets will tend to deteriorate, becoming brittle allowing for leaks. At this point it should be replaced. It is made out of a rubber material and it is sold individually. Replacing this gasket is a quick and easy job. You would need a wrench to complete this repair. • Remove the head cover bolt • Separate head cover and the old gasket • Secure new gasket in place • Reattach the head cover

Loose value (caused by stripped pivot bolt) hitting valve cover, causing valve cover to leak oil.
