Good Morning all.... I have been having a problem with a Hough H65 wheel loader that is running bad. When the unit is cold it seems to run ok, however after warming up to operating temp the issue begins. First , the R.P.M. drops off ,then the engine starts to "sputter" , I begin to get blue smoke , Then the engine dies. I let it sit for about five minutes and the engine restarts and will run ok for about 5 minutes , then the whole thing starts again. I thought perhaps it might be starving for fuel so I changed the Fuel filters. that made little difference. The blue smoke is quite disturbing since it only happens when the engine is ready to stall. I get normal black smoke on full throttle opening but it stops when the rpm catch up to the throttle position. Could there be something in the turbo oiling circuit ? Any help would be appreciated.
Sour running IH dt407 engine
