Low oil pressure causes

[nyoffroad]

My money's on the cam bearings, but it could also be main/rod bearing. Just because it's "in spec" it could still be at the far end of the "spec" as the bearing could be too. Add the two together and you get way out of spec.
Always use plastigage! Some of the dipsticks behind the counter might not know what it is, but it's there somewhere.

Low O.P., turbo or cam?

As I've posted before, I have low oil pressure, 2 psi at a warm idle of 500 rpm. 30 psi down the road. Pressure verified by 3 manual gauges.
I had a loss of oil while driving.
Ted's trucks optimizer, very clean, had great pressure.
Crank was inspected and had no wear.
New crank bearings.
New main bearings.
New HO oil pump.
My Questions:
Can a turbo cause low oil pressure? ( It being the easiest thing on the motor to change, I am hoping so)
Can all but the rear cam bearings be changed with the engine and transmission installed? I expect it would take a special tool to pull the bearings.

The turbo should not cause that much of a pressure loss. I noted no noticeable change in my turbo addition on the 1008. What is the oil pressure "cold"? Now you said the crank was inspected and saw no wear. Did you mic it to make sure the main/rod ODs are in spec? Plastigauge it? Cam bearings mainly cause the issue you're seeing from what I've experienced. And you'll need to pull the engine to replace them. I mean you might be able to get the one near the timing chain, but that'd be it.

his other thread on this has answers to some of your questions.

Crappers. Cam would be my luck. Had the crank mic'd.
