another trend of **** that has been growing larger (or smaller depending which way you look at it) with my car. Only happens when stopped with my foot on the brake....lovely.

Mines about the same when the RPMs are like at 500 or what ever when stopped at a light, but as soon as i just tap the gas it goes right over 40

I wouldnt worry, my Aurora when idling hot is just over 6psi (digital oil pressure monitor). Jumps all over the place under different temp and load conditions, and I've got zero problems.

I'd say your oil pump is ok!

Looks normal to me, for 30 weight oil. If you want it to read higher, switch to 40 weight. But, don't do this in the cold weather areas. I run 40 in the summer, and 30 in the winter. I like the NASCAR theory that higher oil pressure makes happier engines...

BUT 40 IS THE MAX!! And again, base it on your climate, and change it often.

I don't know, Robert. It'* right about in the area where it should be higher, but isn't real low, either. At this point, I'd say keep an eye on it, and hope that it'* not an indication that your annual Thanksgiving LIM gasket repair wasn't too late.

How is the oil looking? Is it still quite black?

so its been a while since I've been on BC...but all I have to say is...joys of a coolant loving motor

Jim...Aurora oil pressure scares the hell out of any normal person.

Rob... Looks like at least 25psi to me. Which isn't "bad" yet. Mechanical gauge is suggested to know the honest reading from it. Our gauges aren't the most accurate and we are well aware of that fact.

I would definitely monitor the pressure. Consider hooking up a mechanical guage to get a true reading. How many miles are on it?

My 99 with 165K never dips below 45 psi.

At least they work...mine just kinda flow back and forth like the flow of the ocean... :P

I'm no mechanic, but I've read before that as long as the PSI is at least 10 per 1,000 RPMs you should be good.
