Re: 87 Oil pump change......how much? (fulopd)
I don't know about having a dealer or shop do it, but if you're mechanically inclined and don't care to get a little dirty, it should be pretty easy to do yourself. I think you can remove the oil pan just by removing the bolt-on crossmember braces, and unbolting the pan. You may have an oil cooler line in the way, if your car is so equipped. Either way, not a big deal. Once you have the pan off, the oil pump is easily replaced. And the pump costs less than $50.
If you pay someone else to do it, I doubt that you'd have more than an hour of labor involved. Probably end up costing $100-$150. Just a guess.

Yep, under the car. It's a dirty job, but mechanically-speaking, easy to do.
You'd have to get the car far enough in the air to work comfortably underneath. Ramps might work-- jackstands would probably be better.
As was mentioned in the other thread: A lot of things can cause oil pressure problems. Oil pumps don't usually wear out before the rest of the engine, so I would suspect other problems. First thing to do (or have a shop do) is get a mechanical gauge and see what the "real" oil pressure is (though if you changed your sending unit, the elec. gauge should be pretty close). What's the oil pressure when cold? How about with the engine warm @2000 RPM? You should never see less than 10psi, even at hot idle.

Re: 87 Oil pump change......how much? (needanother1)
Hot idle, it's less than 10, when driving its around 28, when engine is cold & it's at idle oil pressure is 18. Any ideas?
Basically, the hotter the engine gets, the lower the pressure gets....

do a compression test first, that low psi could be from a few different things, spun bearing, hole in piston, shattered ring. is the car burning oil much? if all is well my advice is a GM or melling oil pump. lingenfelter sells the melling with a high psi spring for under $50

I have low oil pressure, that's why I'm considering a new pump. Changed the oil pressure sender, but that didn't help my pressure problem.......
