I'm dealing with the same problem right now. Have not found any resone for the low oil presure,but it has seemed to fix itself. We went from little or NO presure,to 22psi at warm idel. All we did, was spray W-D40 in the ports to flush them out, reinstall sensers and the oil presure came back.     We installed a new oil pump and pick-up tube, just to make us feel like did somthing. HA HA...

check your piston oil cooler nozzles they are plastic and can sometimes break. there six of them located along the block on the turbo side of the engine . they are hard to see with one bolt holding each
