Good To Know

Q: Does this gasket replace the factory seal? A: Yes, it is produced as a replacement for the OEM 420950820 valve cover gasket on the listed 1503 application.

Q: Can I reuse the gasket after removal? A: A valve cover gasket is intended for one-time sealing, so replacing it during service gives a more reliable seal than reinstalling an old one.
