Those cracks are pretty normal... can you post pics? 3" sounds like a pretty big crack.

yea, in a few hours (still at work). one of them rounds the corner and goes to the Exhaust Manifold mount and the other starts going up towards the turbo

Looks fairly run of the mill to me. Just make sure its not too brittle around the crack.

Extreme heat causes it...something a turbo generates normally.
As long as it not cracked all the way through, you'll be fine. I've got 3 housings and they all look like that. -------------------- 92 Eagle Talon TSI AWD "The Black Golfball" How fast can a 14B go???

It just caused by heat cycling over time. I wouldn't worry about it getting worse. You'll know when it gets too bad when your turbine housing falls apart.
 Seriously though, don't worry about it. |
