Good To Know

Q: How often should this O-Ring be replaced? A: It is commonly replaced whenever the oil filter cover is opened for service or whenever the old ring shows flattening, cracking, or oil weepage.

Q: Does this O-Ring need lubrication before installation? A: A light coat of clean engine oil on the ring helps it seat without twisting and reduces the chance of pinching during cover install.

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