I have a good running '39 flathead that has developed a rust-through hole in the water jacket just below the exhaust manifold's lower bolt on the rear-most outlet. I've read on the Model T site about using the original JB Weld for this kind of problem and also about using a High Temp Belzona epoxy on the Cummins diesel site for patching in these kinds of situations. Do any of the Early V8 community have any PERSONALLY PROVEN solutions to fix these kinds of problems that does not involve using a torch? It's a nice engine and I'd really like to save it. Thanks.
