Hole in exhaust rocker arm for oil sprayThe system was developed in order to provide a stream of engine oil to the injector solenoids. The design uses the existing oil supply from the valve mechanism. The oil spray is directed out of the exhaust rocker arms. There is one 0.7 mm (0.028 inch) hole (1) in each exhaust rocker arm.Note: When you are servicing the valve mechanism, the oil ports must remain free of debris.
