low oil pressure

Define low oil pressure?! ....Ford measures 30 psi at 2,000 RPM's to be Normal...

Also, oil pressure will drop at idol....all depends on the clarences, I've seen some pretty built 5.0's have 20 psi (warm) at idol and still run strong!

Abslutely. Every engine is different so a long as there is a noticable drop in pressure from what you normally see then there is a probelem somewhere. My 360 holds 80psi at idle and goes to about 90 at full throttle. When he pressure starts getting aroung 50 to 60 psi at idle I know it's time to change the bearings. I like to keep tolerances about .0025" on the mains and rods.

Rob you are right with the compression. You also want to look for any variances of more than 10% - 15%.

LOL, I figured you knew about that variation between cylinders so that was more for everyone who doesn't.

Exactly! ...with my old 5.0 race set-up, oil pressure was 90 psi at WOT!! ....pressure would drop to 40-50 psi (warm) at idol....

Thanks guys appreciate all the input
