Good To Know

Q: Does this gasket require sealant during installation? A: Most valve cover gasket installations on the 1503 engine do not require additional sealant, though a small amount at corner joints may help. Always follow the manufacturer service procedure for your specific model.

Q: How often should the valve cover gasket be replaced? A: Replace it any time the valve cover is removed, or sooner if oil seepage is observed. Reusing a compressed gasket can lead to leaks.

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