hi every one I had my xr50 turbo ute for about 4 months. I think the bearings in my turbo are shot it makes a rattling noise when I turn it off is this common. the only work I have had done is alloy cooler pipes, dump pipe, cat, exhaust, 12 psi actuator and tune it runs 16 pis is this the cause of dead turbo. also the car is still under warranty do you think that they will still cover my turbo with work done. cheers michael
