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

Bowman. EARLY 55 V8's had a pee hole in the rocker arm directly above the push rod socket of the arm. It shoots out a stream of oil to keep the overhead well oiled.

The pee-hole was discontinued sometime after early production.

Disclaimer: I have never actualy analyzed any early 55 rockers. Never had one in my hand. My explanation about the early 55 rockers is based on reasonable research and other Packard owners claims.

See the oiling schematic in the manual for the engine. U will see oil path across the top of the rocker ARM.
