Five replacement valve cover gaskets

Valve cover gaskets help prevent engine-oil seepage around the cylinder-head cover. Replace the gasket whenever the valve cover is removed for inspection or valve adjustment, or when leakage is visible around the cover.

These are aftermarket replacement parts and are not manufactured by Honda. Compare your original gasket and engine model before ordering to confirm compatibility.
