Hi all, I spent a fair bit of time cleaning up my transfer case and somehow missed the fact it has a broken piece. It is a chunk missing from the inside of the starter motor mounting hole, I'm sure it won't do any harm but I wanted to repair it- can I TIG it up or will the heat distort the casing and cause me problems? If so am I better off using something like JB weld and glueing a repair piece in made of aluminium the right size, or shall I just leave it alone?
Here's a couple of pics:
