N63 Compressor Wheel Cracks?
I am hoping these are just superficial cracks in some sort of thermal/low-friction coating?
Both turbos show this - Bank 1 is worse, both pictures are of Bank 1. Last edited by borderm3; 12-19-2016 at 06:39 PM.. |

I haven't cracked open many turbos, but that finish wear on the shaft seems a bit out of place?
RE the cracks. I doubt it's structural...it would have blown apart from the RPM. Looks like Alpina snails time!
