Hi guys i was wanting to know what would make a turbo start losing metal off the wheel on the air intake side? Ive disassemble the engine, and nothing broke, the headers are not chipping, but the wheel on the turbo has little peices missing, and i just got it from Jack Cotton. It wasnt smoking, and it had no shaft play, but i am going to check the cylinders to see if it done any damage. Im thinking of putting a 4.1 ive had hear for a while, and i dont want the samething to happen again. No screens out of the MAF ive checked everything. Is it possible for the turbo to spin so fast it breaks apart?
