HH56 Quote:
(snip)[PI] concentrated on the bottom pot metal plate swelling as the cause. Said nothing was wrong the the rest of the pump or the design.
Of course that's debatable isn't it? I'm not accusing Jack, Howard or Keith of defending this modification as being equal to or superior to the Olds pump & adapter solution. For the record, I am just pointing our some known deficiencies of the PI solution:
1. It does not address the normal wear of the housing, gears or upper driveshaft bearing of a 55+ year old assembly.
2. It does not address the inadequate design of the oil pressure relief (too small of a sleeve/spring when compared to the Olds pump).
3. It does not address the placement of the bottom of the pump with respect to the bottom of the pan (Olds pump is at the bottom, Packard is 3IN above).
4. It does not address the probable engine need for extra oil delivery volume due to wear in all lubed areas (lifter bores, bearings, etc.). Even the Olds "standard volume" pump has higher volume than the Packard original capability.
