RE: Turbo Exhaust crack and exhaust manifold gasket leaks.
Could anyone please tell me what the materials are in the turbo outlet flange
and exhaust downpipe. I want to ensure that I specify the correct stick type
for my attempted weld repair (see below).
Thanks in Advance,

Subject: Turbo Exhaust crack and exhaust manifold gasket leaks.
The crack is now as far around as I can see Time for repair!
1. There was a crack (about 1.5"long!) circumferentially around the exhaust
pipe which bolts to the turbo outlet. The crak appears to be located at the
root of the weld.
Can this be rewelded?
If not where would I find a replacement pipe?
2. The gasket between the head and the manifold seems to have blown with leaks
at more than one cylinder. Is it likely that the exhaust manifold studs would
have weakened due to the exhaust leak sufficient that they will break off?
Is there a way to reseal the joint without removing the manifold?
Are there any special practices when trying to loosen the studs?
Will I likely damage the manifold when I remove it?
What is the likely longer term damage if I don't touch the manifold?
Thanks for any suggestions,
