Specs At A Glance

Good To Know

Q: Does this gasket require sealant during installation? A: Many installers fit it dry since it is shaped to seal on its own, but always follow your service manual for the 900 ACE engine. A clean, flat mating surface is essential for a leak-free result.

Q: How often should a valve cover gasket be replaced? A: Replace it whenever the valve cover is removed or if you notice oil weeping at the seam. Reusing a compressed gasket often leads to leaks shortly after reassembly.

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