Re: Oiling system history recap and update on the Oldsmobile oil pump conversion

Packard for many decades employed a "floating pickup" combined with bypass oil filtration, to provide superior filtration with a single filter. Bypass filters filter out smaller particles than do full flow filters. The floating pickup is intended to pick up the cleanest oil as heavier particles sink, ensuring no large particle gets circulated.

I just replaced my pump several days ago with Jack's Olds kit. In addition to the rigid pickup, I also noticed that the pickup sits higher than the Packard original, like about an inch. I take this to mean you won't want to let your oil level get low or you'll soon be sucking air.
