any chance the vehicle was run with BioDiesel? i've seen that stuff
really thin out some less robust oils because of its solvency, even
though it doesn't discolor the oil as much because there's no
particulate matter...
i think i'd change the oil to make sure it's got the proper stuff
in it, then do an oil analysis to see what's actually showing up in it.
cheers!

Well I am now the proud owner of the vehicle in question. I really
dont know what to think about it yet. Poor guy has put a ton of money
in this thing fixing it up. He said at first they thought it was
something with the oil pump, but they took it someplace else in OKC
and the cut open the oil filter and found a flake of copper or
something. So the conclusion was the bearings are worn out. I am
just not sure about that. The car starts right up, runs great, sounds
great, no bearing noises at all. When its cold the oil pressure pegs
right away. I just drove the car a couple of miles and sitting at idle
it does drop to just below the low (15psi?) mark, but pegs again if
you rev it up. To me it seems a little on the low side but not
dangerous. Now a long highway run would probably make a difference.
When I checked the oil it just seemed thin to me. Most diesels I have
ever seen the oil is black black black, even after and oil change. I
think they did change the oil in OKC and its slightly brown, not coal
black like I am used to, and it just seems thin. I wonder if he was
running the wrong weight of oil in the car? I think the first step is
to change the oil again with the right oil and see what happens.
Worse case if the bearings are bad I guess I can pull the engine, drop
the pan and swap them out. I would not think that would be too big a
deal. Or maybe I should try the oil pump first. Can that be replaced
just pulling the lower oil pan?

Well that's good. I was trying to reply last night, but could not
because Comcast apparently thought my email was a "spam bomb." My fear
was that the main bearings were shot, which has always been my
experience on an engine that won't maintain pressure once it warms up.
But I hope this turns out to be a less significant problem.
