starkweatherr,


Your pictures are typical of an old engine in a old truck that hasn't had care or has sat for a extended period of time.

The pushrods are solid. The oil comes from the rear cam bearing via a tube that terminates in the center oiler. The center oiler is located dead center of the rocker assembly. It has a curved overflow tube attached to it. The rocker shafts are hollow with small holes on the bottom which allows oil to weep out between rocker and shaft.

The internal line can and will plug...it has a very small ID and not lots of flow to keep it flushed.
