One of the ports on my exhaust manifold (1959 Case 510B) is slightly warped so that the surface which mounts to the engine is not in the same plane as the other ports on the manifold. There is a gap of just less than 1/8 inch. I think the correct fix is to build up some material on the port's mating surface with a welder, and then flat file the material flush with the other ports so that the manifold will seal.
I've never welded before. I have a Hobart 140 Amp MIG welder that I've been meaning to learn how to use. Should I use argon? Or a flux core wire? What is the risk that the cast iron will crack? Is there a special wire for this purpose (cast iron)?
Thanks,
Colin
