certified mechanic and engine builder who NEVER had a "come back". Questions?

Your point here is moot...

I say that because that's what he said the oil pressure was @ idle with the engine cold.

Not @ idle hot like you are now saying here.

And as far as I am concerned the cold oil pressure data is mostly worthless info for the sake of any discussions like this.

Fact is you did'nt bother to ask the OP what the oil pressure actually was @ idle hot before the "problems" started,and it just so happened that it occured to me that might just be an important bit of info that we actually needed to know here,so silly me I went ahead and asked the OP for that very info instead of working off of any assumptions or such.

Anyhow....

Yeah,lose the FRAM filter,I'd bet $$$$ that if this current filter were to be cut open,that the filter element has collapsed internally,and thus it's restricting the flow of oil to the engine itself,that explains everything in one nice simple answer.

I had a pretty good idea that's what was going on here,but just did'nt want to commit to that specific diagnosis until I knew for sure what filter was on here,and where the op readings were being taken,as this is a scenario I have seen before on other's pontiac engines.
(not mine though because I never use FRAM filters)

Yep,,,further proof that FRAM filters are the "orange cans of death"...

HTH
