I heard this is very common. Most people do nothing about it. But it is caused by high heat .. I.E maybee running lean, clogged cat or somthing. I don't think there is anything wrong with welding it, just make sure it is not going all the way down in your housing. Also fix the heat issue.

This is just things I have heard about this situation.. Im not a expert on it.

 

cracks on the inside are supposed to be 'not so bad'; ie you can still use it. If its cracked on the outside edge, you'll blow gaskets.

hey, I've got the turbo manifold and the turbo off my engine (I blew a seal). It came from an 89TII you could have the pair for $100.

Am i allowed to post dollar figures? If not, I apologize. If it doesn't matter then I don't apologize.

 

i have never seen a S4 or S5 turbo which wasn't cracked in that area, also the manifolds aswell, go over your manifold very carefully

 

Hey Arpus,

I NEED that turbo and manifold. Do you still have it?
