Smoke between shifts

[LaunchHard]

brought the turbo back to the shop because it there was soot in the intercooler pipe and the turbo seemed to have developed some play, but the shop said they dont think there is anything wrong with it and that the soot in the intercooler pipe could not have come from the turbo. Seems like they dont know what they're talking about, am I wrong??

If its not the turbo, what would be the next thing in line to check? As far as PCV, i have a small filter on the passenger side one and I removed the one on the backside, so it vent right into the engine bay. Anything else I can do to relieve or eliminate crank case pressure?
