Broken/ leaking exhaust manifold bolts
I have recently been experiencing exhaust leaks from my exhaust manifold, and it looks like I have a couple broken bolts on the manifold itself, which is where I think the leak is coming from. I have ...

If it is the bolts that hold the manifold to the head, this a a common issue on the LS series. Not sure about the 8.1's....do they have aluminum heads?
The aluminum head LS's are pretty easy from what I hear. My friend has done a few. You just weld a nut to the broken bolt. The heat loosens it up and the nut lets you take it out. And you don't have to worry about welding the nut to the head accidentally because it's aluminum. He says they are no problem...I've never done one.
If it the the stud/bolt that connects the manifold to the rest of the exhaust, I would probably just replace the manifold. I don't think they are that expensive.
If you can install headers, you can do this. Might get the blood pressure up a bit your first time, but it's not rocket surgery. :)
