Weird oil pressure....Help Please ok, Im new, Ive read all the other threads about this, but I was wanting fresh opinions on my particular situation.
1998 LS1 with all bolt ons, ported heads, cam, and slp oil pump. done at Speed Inc.
all of a sudden at idle I have no oil pressure, i can rev the engine and get it to go up to 40-50 or somethin. and then it will drop back down slowly. The SLP oil pump was put on by speed inc in '04 at approximatly 80k. car now has a bit over 100k on it now.
I would appreciate all input, I think Ill take the pan off and check things out....

Alright, well when I first noticed the pressure drop I could rev it and get the pressure to rise momentarily, now it wont read anything but zero and i have alot of noise at the top of my engine. so Im thinking oil pump. but Ive got a SLP thats 3 years old on it.
I have no idea what im looking for to take the oil sending unit off so i can test the oil pressure. is there a possibility of a spun bearing with 100k miles and a cam??
ruined all my weekend plans...

If you have no oil pressure do not rev it until you know it's the sending unit. I wouldn't even run it. If the top end is making a lot of noise, that is a sign of low oil pressure. No oil getting to the lifters and valve train.
There is always the possibility of a spun bearing, but the noise would seem to come from the bottom end. There are two ways, that I know of to hook up a mech. gauge. Either from the sending unit, behind the intake manifold, under the cowl. Or right above the oil filter there is a hook up point, You could also remove your stock sending unit and, with a mirror, check for oil flow with the engine running.
