So, today was pretty cool.
We had a guy bring in his 2005 F350 6.0L diesel for a few issues. The whole story, which we weren't originally informed of, was that less than a week ago he had a brand new Garrett turbo installed. This morning he was driving it an all of a sudden he hears a loud noise in which he describes as a "piston trying to get out". After the noise, he experiences a lack of power and white smoke. He brings this truck in and is complaining of it smoking like a freight train, rough cold start idle, and lack of power.
I start it up and it seems fine with no smoke. I pull out of the dealer and look behind me - nothing but a bluish white smoke. As we all know on a diesel, a blue tint is is likely oil consumption and a white smoke is a lack of fuel or coolant being burned. The truck has absolutely no power. I cant even power brake it and get the turbo to spool up. I grab IDS notice the truck is not registering any boost on the map sensor. I ask myself "wheres the boost?". I pop the hood, look for any obvious CAC hose problems and find nothing but I noticed the turbo is brand new. I decide to take the air cleaner housing off to watch the compressor housing spin - but it doesn't spin at all. After turning the truck off, I reach in and the compressor wheel spins freely. We decide to remove the turbo and what I find is kind of astonishing. I took a picture of it. The exhaust side turbine housing broke clean off the shaft. I had to cut his nice welded 4inch stainless steel exhaust to fish the turbine housing out of it. It made it all the way to the muffler. I do IMAGINE that made quite a loud noise as it spun that turbine at 15K+ RPM down that exhaust pipe.
