I just got my '91 on the road after converting it do diesel from gas. While I had the engine out I replaced the cam bearings, rod bearings, main bearings and rings (turbo, torque cam and studs were added at the same time.)
I'm getting 10-15psi at warm idle (which is fine from what I could find.)
But at 2000-3000 rpm I'm only getting about 25psi, and doesn't really go any higher at governor. Is that way too low?
Measurements were taken at the turbo oil inlet with an electronic gauge and confirmed with a mechanical one in the same spot.
I checked the regulator through the oil filter mount and in appears to be closed, but it's hard to tell. The regulator body rotates and moves back and forth in its hole, the one in the old cooler end does not (I kept the broken part for some reason....) The history of the cooler is not known. It's a craigslist buy after I broke the rear cap trying to disassemble the cooler for reseal.
Anything I'm missing? Should I just pull the cooler and try replacing the regulator with the one from the broken cooler end?
