Sierra Push Rod Cover Gasket 18-2815 for MCM 120/140 4 Cylinder Stamped Lifter Side Cover

The Sierra 18-2815 Push Rod Cover Gasket is a single-piece sealing gasket designed to fit between the push rod cover and the stamped lifter side cover on MCM 120/140 4 cylinder marine engines. It creates the seal needed to keep oil contained around the push rod area, preventing leaks at this common wear point. The gasket is finished in white and is supplied as a single unit, making it a straightforward replacement part for routine engine maintenance or a full gasket refresh.

This gasket is manufactured to fit the specific dimensions and bolt pattern of the MCM 120/140 stamped lifter side cover, so it installs in the same location as the original equipment gasket without modification. Because it is designed specifically for this application, it helps restore a proper seal and reduce the risk of oil seepage that can occur when an old or hardened gasket is reused. It is backed by Sierra's customer satisfaction warranty coverage.
