Ok so Im new to turbos, and Ive got a question that Im sure is prally kinda dumb to some of you. On one of the fins on my compressor wheel there is a pit, it measures about 0.045" across (measured with calipers), and it does not go all the way through the fin. I would post a pic, but i cant get it to work. It is the only questionable spot on the whole wheel, the rest looks brand new, along with the rest of the internals. So, do I need a new wheel?
