Oil pressure

Can anyone tell me what the oil pressure should read in my '84? Maybe a range, say 55 to 60???

You will probably get a mixed review on oil pressure in here.. My 84 xfire with a fresh rebuild shows about 60-70psi at speed, and around 40-50 at idle... Some say my pressure is to high. I am not sure. Ever since I've owned the car (8 years) it has always reflected a PSI over 60. I now have a fresh engine, new sensors, and new digi dash, and im still getting approx. the same readings. I would say if your over 15-20psi at idle, your fine.

I have read - rule of thumb, 10psi for every 1k rpms.. Not sure how true this is though...

After my engine is fully warmed up, I get 20-25 psi at idle (~700 rpm) and around 55psi at 2000 rpm (about 70 mph). That's for an '87 w/ 100K miles.

The 10psi per 1000rpm is a good base line, but it is a bit low.

basically, if it's below that, your hosed.

The numbers that BamaVette quoted are real good... and about where it should be.

My 86 with 105,000 miles is about 65-70 at startup.Then once warmed up @ 750rpm it sits above 40.This is with mobile one 15-50

Spec is 50-60psi warm, with your foot on the gas...and about half of that idling.

In my opinion, more is better, so dont be alarmed if its higher. I wouldnt be worried until the idle pressure drops to single digits or the cruise pressure drops into the 40s.
