Abstract
An aluminum rocker housing (10) is secured to the cylinder head (8) of an internal combustion engine (2) to surround and protect the cylinder valve assemblies (156, 158) and associated rocker arm mechanism. The front face (58) of the rocker housing (10) includes a recessed surface (68) which forms an air intake plenum (60) for receiving pressured air from the engine turbocharger (48). Air intake passageways (84, 86, 88) cast to the rear of the front face (58) communicate with the air intake plenum (60) and simultaneously register with air intake ports (160) formed in the cylinder head (8) to provide a means for distributing air from the air intake plenum (60) to the cylinders (16). A rocker cover (12) molded from plastic is secured to the rocker housing (10) by a plurality of vibration-damping bolt assemblies (13). The rocker cover (12) contains a drip lip (148) to prevent engine lubricants from coming into contact with the rocker cover gasket (14). The rocker cover (12) also includes a means (151) for engaging the gasket (14) to increase the sealing capacity thereof.
