the guy who i am going to take it to 2mo told me that it could be that a shaft snapped or something of that sort because blades are all ok and there is no smoke coming from the exhaust or any oil leaks. if he tells me that it can't be fixed i won't bother with a re-build, i will just buy a new turbo. most prob got pissed off of having 32psi slammed into her day in, day out!
