Good To Know

Q: How often should a valve cover gasket be replaced? A: Replace it whenever the valve cover is removed, or if oil seepage appears at the cover edge. Reusing a compressed gasket can lead to leaks.

Q: Does this gasket require sealant during installation? A: Most valve cover gaskets install dry, though a small amount of sealant at corner joints may help. Always confirm torque specs for your specific engine before tightening.

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