  • PROBLEM.. please confirm my fears

    pull off the intake pipe. then reach inside the turbo and check shaft play. up and down and forward/back. if it has much play it is shot. also the turbine wheel could have broken off. no easy way to check it though.

    If it's a rattle noise at high rpms it isn't going to be your turbo.. they spin at 100k+ rpm's, it's going to be a constant sound if it's the turbo going out... it's probably something loose.

        If it is pick up slow, maybe the turbo is frozen

        Terrible idea putting those wheels on...

          when my buddies ko3 turbo went out on his audi every time it hit the housing it made what was very similar to a fast buzzing sound and the car lost a shit load of power when it happend every time it spooled.

          you may have a rod bearing that is going out. that sounds like a rattle. but it doesnt really sound like it comes from anywhere. then when it does go out eventually it sounds like knocking. but that wouldnt make it pick up truck slow
