Too much turbo shaft play??
I just picked up a used B&G turbo kit for my fox. It has the standard MP T-70 with it. The impeller and the turbine appear to be perfect, and if I spin the shaft it spins freely with no noises. BUT, I can gently push the impeller to the side of the housing and cause enough interference that you cannot freely turn the shaft anymore. As soon as I release the easy side pressure, I can spin the shaft freely again with no noise.
I know that there needs to be some play (clearance) allowed for the oil, but I've never seen the play cause interference.
Will this thing be OK once oil is fed to it during normal operation or is this a ticking time bomb?
Let me know what you think.
