Hi, GTO,
If everything on a rebuilt engine is to spec, the first two design changes the Packard engineers made will give quiet running and good oil pressure. Craig/Eric are correct in that the Packard pump does wear prematurely and does not have the capacity of the Oldsmobile pump to compensated for wear in other parts of the engine. Your pump may be worn, or you may not have the second design plate/spacer, thus, your lifter noise. Change them both while you are at it.

Correct.They do not rebuild the pumps.They just modify them.
On most Packard V8 pumps I have seen, the drive shaft housing bore is the worn part. Often, the gears and the gear cavity are still within spec. Modifying the shaft bore with a longer bushing may be all which is needed to return the pump to service.
Hi, Craig,
Just today, I got an order to rebuild a Packard V8 for a 1956 Studebaker Golden Hawk. He wants the Oldsmobile oil pump instead of the modified Packard pump. Do you have one more kit left?
thnx, jack vines
