Turbo exhaust housing cracks
 

Okay, I have bought 3 S4 turbos now and every freaking one has a cracked exhaust housing. Is this just extremely common or is this slightly normal. There are two small cracks on the Turbo/block side but there are 2-3 cracks on internal divider. Are these housing still usable.

I dont know if they are usable, however its pretty common on all old turbos that have seen a decent amount of usage (heat).

I would highly doubt they were usable, and wudnt be the one to want to test that theory either
