If you think you have oil pressure gauge issues-read here!!!!
Guys, the stock gauge is notoriously inaccurate so before having a heart attack, buy a cheap mechanical guage and install it temporarilly so you can see what is going on, then you can panic or not. Another but not foolproof way to tell is if you have low oil pressure, the lifters should be noisey.
Oil pressure at idle should be around 10 psi or higher, and rule of thumb is 10 psi per 1000 rpm, 4 psi is the bare minimum and if your over 100 psi, the relief valve in the oil pump is stuck.

The electronic after market gauges are not reliable either. I have an autometer electric gauge in my SC that is about as accurate as the stock gauge; even after I sent it back to be recalibrated.

Yeah, my aftermarket gauge says I have 8 psi at warm idle. The engine isn't noisy, so I'm not too concerned.

Heh, I should probably stick a warning label in my minivan before letting anyone else drive it then, oil gauge has been reading zero for years, only twitches up just above minimum for 5 minutes this weather when it's cold. The idiot light seems to work fine.

i have 91 shadow instaled a mechanical oil pressure and runnin any were between 50 to 70 psi when cold and 20 to 30 warm over since oin change with luc oil stabalizer now if i take a corrner any faster than 20 or 30 kh it dipps down to 15 or 20 psi and oil light comes on then goes out also i hamered on it the othe day and the moter bogged down half way to 110 and oil psi dipped to 15psi flashed light i let off and psi went back up and then tweeked between 40 an 30 psi till i got to the junk yard could this be a bad oil pump?????

You either have low oil or the balance shafts have been removed and the oil is sloshing away from the oil pump pickup, NOT good.

didnt come with counter balence shafts(2.2) iol is full

I would drop the pan and check out the oil pickup.

I was under the impression that all engines except TIV, TII and L body's got balance shafts?

moter is a tbi out of a 88 laberon until i get more money to finish TII build i have only seen thoes in 2.5 but i wouldent dought that they came with

Only the 2.5 TBI's got balance shafts.
2.2 TBI's (and the 2.5's in the Dakota) came without them up until the end of their production in 94/95.
The 2.2 TBI's weren't used in much else besides L-bodies and Shadow/Sundance Americas in the later years, which is why you probably thought they were an L-body only thing.

Don't forget the easy stuff too. Make sure the contact on the sending unit is clean AND tight. If it isn't tight then it'll read low and jump around.

Simon, you know that I know that you know that TIVs have balance shafts. You have seen them in my car.

I have? Maybe on Sat I will, :eyebrows:
Re: If you think you have oil pressure guage issues-read here!!!!
What year did they go with the 2-wire pickup? I'm still learning about the 4 bangers. My '86 has a 1 wire. It connects up like the temp pickup for the temp gauge. That's the one I'm talking about above and they can get dirty and loosen up. The 2-wire, well, then, that might be broke for sure if it doesn't work.
Re: If you think you have oil pressure guage issues-read here!!!!
wow im seein some staggering numbers compared to my autometer mech gauge, my readings are 55 psi at idle and after fully warm im never below 20 psi at idle. Its new gauge too. do i have an issue or something? driving when full warmed up at highway speeds etc im around 55 psi.
Re: If you think you have oil pressure guage issues-read here!!!!
and i just realized this thread was from last year haha. So anyway im surprised the pressures are that low stock. Mine are much higher as stated. Im sure im not the only one. Or do i have an issuie with something causing the high pressure?
Re: If you think you have oil pressure guage issues-read here!!!!
My rebuilt engine had 5psi at hot idle, around 40 on the highway. Verified w/ a mechanical gauge. Never gave me any problems.
