Abstract: A manifold body for an internal combustion engine. The manifold body includes an EGR cooler cavity adapted to receive an EGR cooler, an oil cooler cavity adapted to receive an oil cooler, and an air intake manifold configured to provide a gas mixture to the internal combustion engine.

Abstract: A manifold assembly for an internal combustion engine. The manifold assembly includes a manifold body and first and second housings. The manifold body includes an EGR cooler cavity, an oil cooler cavity, and an air intake manifold. The first housing is adapted to provide a fluid to the EGR and oil cooler cavities. The second housings is adapted to receive the fluid from the EGR and the oil cooler cavities.

Abstract: A sectionalized rocker arm cover assembly (10) is utilized for diesel engine (14) applications having overhead high pressure fuel lines (26). The fuel lines (26) connect to fuel injectors (20) that protrude through a primary member (16) of the rocker arm cover assembly (10). The rocker arm cover assembly (10) is sectionalized longitudinally. Sectionalizing the cover assembly (10) obviates the need to dismantle the fuel lines (26) and permits easy access to service the rocker arms (29). The injectors (20) are disposed longitudinally and provide vertical support to the rocker arm cover assembly (10).
