Sounds like all may be well, and I'm glad to hear it. I'm not saying that the pressure relief springs don't sometimes fatigue, just that there are other possibilities.

Thinking to your comment on cleaning the oil pan, I can't think how many times myself and others have suggested to folks with a Packard and without prior history that they should drop the oil pan and clean it out. But I myself was negligent with that same advice on my own 56 Caribbean for some time, though the engine was quiet and had great oil pressure. When I finally did drop the pan, it was relatively clean, BUT the intake screen on the pump suction was about 1/3 blocked off with sludge.

It can be a bit of a pain on some models to drop the pan, but the cost (gasket) is cheap and it's really almost an imperative if you haven't already done it. Nice feature of the 39 and back Classics is that there is an access plate in the oil pan for this purpose (cleaning the screen that is).
