Exhaust manifold

["dgb" <dbilesky@home.com>]

A hole erupted in my exhaust manifold.
It is next to the machined surface for the stud on the left.
The area is quite thin of metal and the hole got bigger as I cleaned it up.

The hole is now the size of a pencil eraser.

I try a high heat putty compound from the inside... but that did not work.

Ideas?
