Low oil Pressure
Low oil pressure 6.0L t76 front mount
Truck idles at 40 psi when cold, it comes down to 20 psi when it warms up. its a stock 6.0 stock cam. Wont go past 40 psi at WOT
Tried going to heavier oil 15-40 didnt help, changed out the O ring on the pick up tube, It has a new GM oil pump
Checked the pressure manually thru the -4 fitting on the turbo feed line which is coming from the side of the block, and it reads correct
Anything else i have missed? Bad Cam bearing?
