Thanks for the input the truck had 66K on it. Does it matter that the turbo spins perfectly?
Also, are you saying that the staining could have been caused by oil without debris/dirt
The oil on the inside of the blower intake/turbo mount seems to have come from the blower vanes up as the actual inside of the intake manifold was quite clean from the turbo to the last part of the manifold. That was why I leaned towards blower seals and away from turbo seals. It just eludes me why the turbo inlet isn't dirtier if the intake boot was allowing unfiltered air into the motor.
Whether or not coked sludge is capable of looking like these pictures without dirt/contamination seems to be the 5-10 thousand dollar question. LOL! I have spent too much time today researching different types of sludge and their respective causes and it still seems a toss up. Some oil sludge buildup is caused by water mixing with oil, some from idling too long, some from operating too hot, some from too cold, some with dirt and some with antifreeze. Kind of a brain freeze for me...
What kind of charge for a rebuilt turbo? Anyplace you recommend?
I am planning on pulling the blower over the next week but I can't do it until I can get the motor pressure washed there's too much caked on junk on the motor to risk contaminating it even more than it possibly is now. Isn't it funny that everyone on ebay always takes a picture of the parts that aren't caked with greasy junk? I certainly didn't expect this motor to be as dirty as it is. Dump truck/ heavy equipment folks don't seem to mind that stuff as much as bus nuts do.
zero, why did you ask about the mileage? Also, what are the black circular marks on the intake housing of the compressor side?
Thanks for your help... I appreciate it
