My neighbor has a 99 7.3 that he recently bought, He says its always been lacking power. Two days ago is started blowing heavy white smoke at all times, mostly at idle after being warmed up, found out today from a diesel mechanic he doesnt know that he had a hose clamp on the inlet turbo lines loose. They have told him his turbo is most likely smoked, does this sound right? We are going to look at it more tomorrow but would this cause white smoke? also he was told that the turbo on his 99 is smaller then later years. Please help with any input, I am going to look into his MAT sensor tomorrow to see if its bad.
Ok, I was wrong on hose position. the hose to the driverside head was connected but the clamp was completely loose. I dont think this motor has been dusted with this scenerio. a mechanice has told him the turbo is smoked since it has been over spun since it has been free wheeling since it has had no back pressure, does this sound right? also, what effect does the turbo have on oil in the exaust, there is tons of oil coming from the end of the pipe, would a shot turbo cause this?
Yes, the turbo gets oil through the pedestal. If the seals go out, you will be sucking that oil in and through the entire system...out the exhaust causing HUGE amounts of white some. Had the exact thing happen to me about 2yrs ago. When I turned the truck off, I could hear the turbo scrubbing through the exhaust. And if I wasn't in a bind, I would have put the GTP38R in instead of OEM turbo.
