Good To Know

Q: When should this O-ring be swapped out? A: Swap it any time the oil filter cover comes off, or at the first trace of oil at the housing. A new O-ring helps stop repeat leaks.

Q: Should I oil this O-ring before fitting it? A: A thin smear of clean engine oil makes installation smoother and prevents pinching. Verify it matches your engine before ordering.

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