Thanks for the info. I was just referencing what the tech told me. I do have a question for ya. Will adding a catch can help with oil entering the turbo? I know people praise catch cans and then some say it doesnt do anything helpful. Im not entirely sure with all the research Ive done, but advice would be much appreciated!!
Did they say there was oil between the air cleaner and inlet of the turbo?
Yeah most likely a bearing failure first then oil leakage. That video would be interesting to see if possible.
Working on getting it to open/ download
Ok, some observations from the video. Particularly the compressor wheel damage. It looks like bearing failure allowed edges of compressor wheel to make contact with the housing. The nut for the compressor wheel is missing. Leading edges of the compressor wheel are damaged (dings) along with the inlet neck of the housing. Most likely the nut worked itself off after the compressor wheel made contact with the housing causing the dings to the wheel and inlet of the housing. The nut is left hand thread and self tightens as it rotates normally. When the spinning wheel contacts the housing it stalls the shaft and can make nut unthread. The nut then bounces around in the housing causing the dings.
That’s up to you. But I can pretty much assure you that a lack of a catch can had nothing to do with this failure.
No but if he installed a vent to the atmosphere bov I wouldn't rule that out as contributing factor. Modern turbos are generally robust but they do depend on proper balance to maintain longevity, running higher than stock boost levels and suddenly dumping pressure can create unbalanced forces on the turbine and compressor side. Know a guy who was running high boost on his modified audis and went thru 2 turbos so he went back to a bov that vented into the intake and no more blown turbos.
I do have a BOV for the last 8 months. The problem with trying to diagnose the issue is it literally could be anything. The best I can do is ask when I go pick up my truck what could have been the problem. I know I did ask if anybody else had an issue initially because of the black smoke. I also did want to document this so that if anyone else was going through a similar situation this could help as a solution. I will report back once I get the full scope of how it happened. Appreciate y’all!
I wouldn't hold my breath expecting that they can precisely determine what was the root cause of the failure, it might even be something from the factory, but running high boost levels and even a slight imbalance in the turbo can start down the path of eventual failure.
