SMOKING BLACK 6.0

[KBS117]

SORRY FOR THE CAPS, KEYBOARD IS MALFUNTIONING. 6.0 IN A 2003 1 TON DUALLY WITH 245K MILES. REPLACED THE HIGH PRESSURE PUMP 5K MILES AGO. RUNNING PERFECT, LEFT IT SITTING 6 WEEKS, AND WOULD NOT START. NEW BATTS AND STARTER ON IT, AND IT CRANKED OVER GREAT. GLOW PLUGS SEEMED TO BE WORKING, BUT NO START. SEEMED TO BE OUT OF FUEL. NO SMOKE WHILE CRANKING.
FINALLY, USED EITHER ON IT AND IT FIRED OFF, BUT MISSED AND JERKED FOR AWHILE. NOW IT SMOKES LIKE A FREIGHT TRAIN. IDLING IT SMOKES BLACK SMOKE SO THICK YOU CANNOT SEE THROUGH IT, AND GOING DOWN THE ROAD IS LIKE FOLLOWING A FOREST FIRE. BLACK BLACK SMOKE. WOT IS FINE, GREAT POWER, BOOST IS AT 24-28 PSI. AT 60 MPH THE BOOST IS AT 6-10 PSI. IT IS MISSING AT IDLE A LITTLE NOW, AND HAS A TIMING KNOCK ON 1 CYLINDER AT LOW RPM.
TOOK IT TO FORD, THEY SAY IT HAS 3 INJECTORS STUCK OPEN ON THE FUEL SIDE? HOW CAN THIS BE? THE FUEL RATE IS CONTROLED BY THE TIME THE SPOOL VALVE IS OPENED ON HIGH PRESSURE OIL SIDE OF THE INJECTOR. IT ALSO HAS MADE 3 QUARTS OF OIL IN 50 MILES, WITH NO COOLANT LOSS. IF THE INJECTOR SPOOLS WAS STUCK OPEN FROM DEBRIS FROM THE OLD HIGH PRESSURE PUMP, WOULD THAT NOT CAUSE A DEAD MISS IN THOSE CYLINDERS? INPUT NEEDED. THANKS KEN

sounds like you have some pintals stuck open in a few injectors or tips blown off dumping way too much diesel in those cylinders. Excess is probably draining by the rings, increaseing the oil level by diluteing it.

Better get it fixed right away! If you keep driving it, you'll will destroy the engine. I've seen pistons melted and complete distruction due to stuck injector pintles, on 6.0's
