Hi everyone, just purchased 1934 Buick 57 series got it on the road with the road worthy provided by previous owner. Absolutely beautiful condition(real head turner) started driving a few friends around and the first thing everyone notice was it bit fumy in the back.Turned out to be the center manifold attached to the rear manifold had hole in it which had had previous work done on it. Tried to weld it with cast iron rods then stainless steel rods after preheating,did not take The whole center manifold has broken off. Looking for ideas and ways to fix the center manifold any advise would help. Cheers Boges
