i installed my turbo 5000 miles ago(t3/t04E) theres was a small amount of shaft play before installation and the the blades spun freely no problem i started hearing a rattling noise like a rain stick and checked the turbo and now theres a pretty good amount of shaft play and the blades spin but not as freely as before the blades are definately scraping against the housing slightly in the compressor when im driving plus i smell burning oil since this happened do i need to rebuild my turbo or? just curious im pissed
