Nothing against your friend, but he doesn't seem to know much about motors.
Your oil pump works. Proof is that cold you have pressure. As soon as the motor starts to warm up and expand the space between your rod bearing and crankshaft becomes larger and more oil leaks out instead of building pressure.

this happened on both of my chevy corsicas. slowly they would be able to run for less and less time, until eventually they could only be run for about 5 minutes before they stall out and the oill pressure drops to 0.

Often it is cheaper/less work to drop a new motor in than to do a proper rebuild. I think 2 large is a bit high for a used motor, but I could be wrong. FYI, unless you plan on doing regular oil changes, you should see if you can get a discount for buying 4 or 5 L67s.

oil
good point. I change my oil every 3k and have yet to have any mechanical engine trouble.
My 80 Buick still has the original 2.8L and runs like a charm 25 yrs.
Too bad I have to sell it though.

Seems like a good idea.

2 grand is way to much. 500-800 is normal going rate

Not sure what your friend is talking about...
Starting out with half decent Oil pressure only to have it drop as the engine warns up a bit tells me that your bottom end is toast...
He can say Oil pump if he wants too, But its already too late for that, you have a Rod knock..
Either rebuild it, Buy another motor.... 2K seems expensive to me... I'm not a fan of Autozone at all, but you can get a reman with a warranty for less than that I'm sure... I know a guy that replaced an L36 in his firebird for less than $1000 with a warranty...
You can rebuild the engine, But if you do it you should take the time and do it or have it done right... The crank may be damaged beyond repair and if it is you would have to have a crank kit.... Then all of the rods should be dropped off at the machine shop to be resized...
And for the bearing replacement... I do not consider it a wise choice to do this on a crank that has wear on it, let alone being scarred which I am totally sure it is... The bearing will never last....
Do it right the first time or pay a lot later
