Father's car: The car is a 1995 325i w/ approx. 160,000 miles.

Upon starting the engine, a very loud, repetitive squeak-like sound comes from the engine bay. I removed the accessory belt and ac belt to try to elimate the possibility of the sound coming from a pulley, roller or belt. Started the car after everything was removed and the sound is still evident. Shut the engine of within 10sec and I noticed a burnt smell.

The only thing I could think of is the oil pump is bad causing no lube to the top of the engine.

Any ideas?

thx

Ok, tommorrow we are going to drop it off at the dealers. I just wanted some insight before we took it there so we dont end up spending a lot more $$$ than need be.

any other ideas?

squeeking? Like a loose belt?

I've read about rear main seals that suck in air and cause the same sound. Try pulling the oil cap when it's doing it. If it changes or goes away, I'd put a few bucks on that.

Similar to a loose belt or even a bad pulley. Actually, its more of a friction-like squeaking... almost like metal on metal. It sounds nasty.
