I recently purchased a 2001 2500HD duramax with 210,000 miles on it. I bought it knowing that it needed a turbo because it poured out smoke and oil out the tailpipe. I just swapped a good turbo on the engine and started it up and it does the same exact thing as before. I know the old turbo was bad because there was so much play in it that the props were hitting the edges and even had some small pieces missing on the edges of them. My next question is what else could be causing this much oil out the exaust? I started it up today and revved it up some and it ran away on me for about 10 sec or so till i managed to plug the intake up with my hand and there is oil thrown a good 30 feet behind the truck. Im thinking it could possibly be a hole in the piston? Im looking for anything that could cause this issue as im prettymuch clueless at this point, i was really hoping to put a turbo in it and be good to go. thanks in advance and heres a few pics of the old turbo.
