Introduction
The problem that is identified in the technical information bulletin that follows does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
In order to extend the life of fuel injectors on the above listed engines, the injector solenoids need to remain cool.Solution
Illustration 1 g01404067
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.
