ABSTRACT:
An improved rocker arm cover assembly having an enclosed rocker arm chamber housing and a generally L-shaped bracket for mounting multiple coils to an exterior vertical side wall of the housing, so that the coils are exposed and laterally displaced from the housing. The bottom of the housing includes special seal and flange members to permit sealing mounting to the engine head so that the rocker arm chamber is isolated as a “wet” enclosure from the coil bracket assembly. The housing is mounted directly to the head via a plurality of through bolts. A fully isolated, dual function, oil fill/PCV valve conduit is provided through the top of the housing to permit adding lubrication oil or permitting exhaust of crankcase vapors without contaminating the coils, and permitting independent servicing of the coils. Several variations of coils and coil mounting brackets are disclosed.
