Cool 6.0 Oil Pressure Problem

Ok, I think I have more than one problem here.

#1 Oil Pressure gage on shows 0 (off) at idle and center at anything above idle (on).
#2 Looking at the ICP Pressure it is close to the desired pressure until you get above 2750 rpm then it drops to about 600PSI with the ICP regulator commanding 85%. Through the rpm range below 2750 the HPOP is making upto 1800 LBS of pressure.


The low pressure oil pump, ICP regulator and the High pressure discharge tube has been replaced.

Anyone have any ideas?

Seems like you still have a HP oil leak. What year truck? You might need to do the air pressure test to find the leaks.

I am going with a leak somewhere as well. 1800psi from the HPOP at 2000rpm seems low to me. Maybe Cheezit will chime in soon.
