Good To Know

Q: Do I need to replace this gasket every time the timing cover comes off? A: Yes, a gasket that has been compressed and heat cycled should be replaced rather than reused to prevent oil leaks. Always clean both mating surfaces before installing the new one.

Q: How do I confirm this gasket matches my engine? A: Cross-check the OEM number 420931130 against your machine before ordering. Fit can also vary by serial number, so verify against your model's parts listing.

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