Good To Know

Q: How often should this O-ring be replaced? A: Replace it whenever the oil filter cover is removed, or at each oil and filter service interval, to maintain a reliable seal.

Q: Can this O-ring be reused if it looks fine? A: Reusing a compressed or hardened O-ring can cause leaks, so fitting a fresh seal each time is the safer practice.

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