I just had my TA-49 Turbo rebuilt and it had a hard failure. Started to blow oil into compressor side and compressor wheel contacted side. This turbo did not even have a hundred miles on it. This failure happen on the way home from the track after four runs. Anyone have any idea what could have caused this and what I could do to prevent this again? The rebuild cost me 425 bucks and I feel that it should have lasted a lot longer than 100 miles.
