Specs At A Glance

Good To Know

Q: Should the gasket be replaced every time the timing drive cover is removed? A: Yes, a fresh gasket is the reliable way to reseal the joint, since a used gasket may not compress or seal evenly again. Replacing it during cover removal helps prevent oil weep afterward.

Q: Does this gasket require sealant during installation? A: Follow the service procedure for your engine, as some cover joints call for a dry fit and others specify a sealant at certain points. Surfaces should be clean and free of old gasket material before the cover goes back on.

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