I have a cummins 4BT,I have 55lbs of oil pressure idle but I'm not getting oil to my turbo, could this be a stuck oil plunger??
Not aware of any plungers that could get stuck. There should be a feed fitting in the oil cooler to a line to the turbo. You could try take the oil feed line off and seeing if it is plugged. If it is good, take the fitting out of the oil cooler and see if it is plugged. -Sands
