1st, stock guage sucks. Hook up a mechanical one to it. I think they're like 20 bucks at autozone, on my 50 I had one and just mounted it under the hood, just to check it w stuff like this. Are you getting any noises at all? If u didn't have oil psi you would deffinatly know lol. I'd check it w a real guage 1st, and go from there

alright thanks ya that makes sense it isnt knocking or anyting the other day it made a funny knocking noise once or twice but it never did it again.. I figure if it had a knock or somethin it would be doing it constantly right?

the car will run without any oil pressure at all. it wouldnt be "acting funny". If it had no oil pressure you could drive it for a few minutes then it would spin a rod or main bearing and start slapping the rod against the block

DR.DIESEL

could failing oil pressure sending unit.its common on the truck engines and they use the same sending unit.

+1 I don't even use the stock oil pressure gauge it always goes up and down randomly. It's definately the gauge (in my case) because it's been happening for a while and if it was actually an oil pressure problem I wouldn't have a running motor by now.
