Good To Know

Q: Do I need new gaskets with this valve cover? A: Fresh gaskets are recommended whenever the cover is removed so the seal seats cleanly. Reusing old gaskets can lead to oil leaks shortly after installation.

Q: Why does crankcase vent hardware matter? A: A restricted or leaking vent path can cause oil mist, rough running, and pressure buildup. Replacing worn hardware restores proper ventilation.

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