Re: Packard TSB 56T-20 - Low Oil Pressure

Keith, like you I wondered at the drawing that showed oil being routed across the ridge on the rockers. When I did the heads on Best Other I borrowed several rocker sets from Owen Dyneto and installed 55 exhaust rockers. My thinking was same as yours. An expert mechanic told me that if there was a mist of oil in the rocker area that would be sufficient lubrication between the rockers and the tip of the valve stems. The hole in those rockers is VERY small. I don't know if it helped, but it couldn't hurt.
