Common Installation Problem

    Compressor Wheel Damage

    When re-installing the turbo, be sure that you take out any rags anything else you used to block off any inlets or intercooler hoses.

    Your old turbo's Demise

    But if you killed a fairly new turbo for no apparent reason, think about what could have been the cause of the turbo's failure. If you simply bolt on a new turbo without fixing the problem, don't expect your new turbo to live long either.

    The Shaft is Rocky

    There is a gap between the shaft and sleeve and a gap between the sleeve and housing. These two gaps combined allow the compressor wheel tip to move side to side in what may look like an alarming amount. This is normal. As long as the wheel is not touching the housing, you are fine. There should be no play axially (in and out) with the compressor wheel and shaft.

    James Bond Smoke:

    You were doing some grinding or porting near the motor with the turbo removed. You blocked off the turbo oil drain pipe with a piece of tape. You forget to take the piece of tape and install the turbo. Start it up and instant James Bond smoke. The oil flow into the turbo has nowhere to go and gets pumped out the bearing seals. If your turbo does this, check the oil drain for blockage, remove it and start it up again. The turbo will be fine, it will take a few minutes of driving to burn out all the oil from the exhaust system. Also a plugged up crank case vent will cause excessive pressure to build up in the crankcase. This prevents the oil from draining out of the turbo and blows the excess oil out through the turbo seals.
