ABSTRACT:
The disclosure illustrates an isolated rocker arm cover for an internal combustion engine. An elongated continuous elastomeric seal element extends from a groove around the periphery of the rocker arm cover. Spring loaded fastener assemblies resiliently hold the cover against the engine with a sufficient force to provide an effective oil seal but still maintain the cover isolated from the engine. The seal element has a configuration assuring a narrow contact area between the ring and the engine.
