Hey guys, just recently noticed that after a pull, when I let off I looked back and noticed some smoke in the rear view mirror during the pull its clean just after letting off this happened. It wasn't a crazy amount but enough that it made me pay attention to it. I'm going to check for shaft play to see if there's an issue there. At Idle in almost sounds like the turbo has a chirp to it. But when I turn the car off it still sounds like its spinning freely as I can here the wheel spinning smoothly after the car is off. Just curious if there's anything else I should check or should I also compression test it?
