hi guys ,i've had my 7020,404 motor rebuilt last month,on the way home the turbo went out ,it was only 2 miles away so i finished the drive,anyway behind me was the largest cloud of smoke i'd ever seen when it went,
well i put a new one on and have been allowing the motor to run daily at about 1000rpms for several minutes at a time,friday i took it for a ride and after i guess it heated up the engine,well the smoke started up again,
the engine builder told me theres oil in the aftercooler and in the pipe that still needs to be bvurnt out and this is going to happen after the motor warms up,and the pipe is hot,the turbo seller told me it needs to be ran harder instead of letting it idle so much while i'm doing other things to the tractor,thanks ,any answers as to what i should believe in?
