Good To Know

Q: How often should this O-ring be replaced? A: It is best replaced whenever the oil filter cover is removed or at each oil service interval, since a flattened O-ring can allow oil to seep past the cover.

Q: Should I lubricate the O-ring before installation? A: A light coat of clean engine oil helps the O-ring seat without twisting, and it should sit fully in the cover groove before the cover is tightened.

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