While cranking there is a hard spot, and blue smoke when it did start. Engine run ok for a few minutes, seemed to be running good except for oil smoke, then quit running. While checking it out i noticed oil running out exhaust. I checked the turbo as it is the first culprit and turbo seems to be OK. The engine acts like it is locking up, I suspect hydrostatic lock. My question is it possible for oil in the hydraulic injector to go through combustion cycle and out exhaust?
