1994 pontiac firebird with low oil pressure, the seller states car had a "stuttering" performance and low oil pressure and that the car was parked as to not further damage. I feel confident in my ability to change the oil pump, if thats the problem, but the car has 202k on a 3.4 engine, so what kind of crap can I expect to find...... I guess I mean to say if its not the oil pump, after I have the oil pan off what can I look for and will it be obvious, I mean what do I need to be looking for.

At 202K miles, it's do for a rebuild. low oil pressure means excessive bearing clearances. You'll more then likely need more than just an oil pump.

If I do most of the work myself, can you see me getting out of this for less than 500?

Long block from a good builder. You can do all the work yourself and rebuild yours, but I would use it for a core if I wanted just a stock replacement. Of coarse if you rebuild it yourself, well, use your imagination. Good Luck!

You can download the 94 factory shop manual at the link posted in a topic at the top of the 4th Gen section of this web site. It sounds like you are gonna need it.

I just had some work done to my 428. almost $3,000.00. $500 won't get you much as far as a rebuild. Personally I'd just get another engine, preferrably low mileage, one you can hear run. be so much quicker too.

Yep sounds like you will need a new engine soon on that one. That's why he's getting rid of it
My bird is a working progress. New Marshall engine-forged pistons, upgraded rockers and stronger rods/bearings. Rebuilt transmission. New LSD. I wish money grew on trees :)
