Default Oil Pressure

I just want to say thanks to the forum for all the info that is published on here to help people out. I bought my 95 Z about 2 years ago with 38,000 miles and it's always had a low oil pressure reading. Not bad low, but low.

Recently it started reading real low, but no low oil light. After checking on here I went out to the car to check the switch by the oil filter, when I tried to unplug it the top part of the switch almost fell off in my hand.

One order from Jerry's Gaskets and today I now have great oil pressure. What I thought might be a big problem turns out to be a piece of cake all because of the forum brotherhood.

Looking forward to the gathering in May at Bowling Green.

Thanks Again folks.

After replacing mine a few times I investigated the failure mechanism and came up with a fix. No failure since.

Yea, I'm glad it was a simple fix.

The complete black top of mine disconnected from the metal base, no fixing.

Mine freaked out on me one day last year and was reading near 0psi when hot at idle. No light though. Which FREAKED ME OUT for sure!
Got on here - asked the question, got the answer, ordered new one from Jerry, Problem Fixed!
I love this place as well!

I'm having the opposite problem, I start mine up and it is at max 80 psi at idle, after a good amount of time it only starts to drop to 70 psi and then 60 when fully warmed up. I put in Amsoil 10w-40 back in November but never really took notice of what it was before the change. Should I be concerned?

The senders can fail both reading low or high.
My first one (in 97) always read as yours, high.

Not only the screwy readings,
but they usually leak too...

Default Re: Oil Pressure

I went through about 3 or 4 different senders a few months ago trying to find ones that matched up with the actual pressures I was getting in the car that I verified with a mechanical gauge tapped in at the sender location.

I have a new Delco one that I didn't check, but all of the parts house ones either read way low or way high. The one NAPA carried is calibrated correct and that's what's in the car now. I have the Delco one as a spare.

Are the rest of you running AC Delco sensors?
