Hank is right about the welding technique. The manifold probably has not been welded properly. As a weldor by trade I have seen many real poor attempts at welding just about any thing. As Hank stated there is a proper technique when welding cast iron and exhaust manifolds are the worst. Your manifold can most likely be salvaged if done properly. the "miracle cure" POR 15 will only stop a leak. It will NOT give any strength to the casting when the generator is hanging on it. A competent weldor should be able to fix you up. Also the manifold should be planned after welding. Good luck!!!!!!!!!!!
