Big16g... What should I do?

[jemsoccer]

So I bought this from a friend of mine and he did not tell me that it was cracked. What do you guys think I should do w/ this housing? Weldable? Or should I try to find a new one? Also, the picture of the stud that says "swivels", the stud actually swivels in the hole and will not thread in or out . I thought about drilling it, but that won't work if the thing keeps moving around. What is that? Was it just a normal stud that got really really messed up? Any help would be appreciated. Thanks guys!

I media-blast all of my turbo's internals with baking soda. It's suprisingly abrasive, and removes carbon like magic while leaving the surface underneath baby-smooth.

You could probably sandblast the turbine wheel itself, but that's all I'd do with sand (not the seal groove or shaft where the journal bearings ride). Even at that, you're putting pits in the wheel that would make carbon easier to "stick" to.

Baking soda... haha, that's interesting. Yea, I wouldn't blast the shaft or seal groove, I'll probably just wipe them down w/ some solvent.
