I agree on the oil pressure relief valve being the culprit since the oil pressure came back up. However, there's no telling when the problem will rear its ugly head again, but this time permanently sticking open with resultant zero oil pressure. It's best you drop the pan and inspect the "unknown replacement" oil pump. Unless it's an Olds conversion, I'd not trust it since the rest of your engine is currently running well and you'd not want to ruin it.

Hi Craig -
Believe me, that car isn't going anywhere until this is sorted out. My thinking on the pressure relief vale is based in part in that both times this happened was after I had to floor the loud pedal. Calm sedate little old lady driving doesn't seem to trigger it. Never the less, I will be inspecting that pump.
If that does turn out to be the culprit, how does one go about scoring an Olds Conversion pump. I really don't like not knowing what something as vital as an oil pump came from as is now the case - I'm thinking seriously of swapping it out on general principal. As you said, the engine is running so sweet I don't want to mess it up.
At least I still have my '51 to fall back on if my need of a Packard "fix" gets too intense.
If there are any other thoughts out their, please jump in!
