I'm putting together a 68 1/2 ton longbed, 350 V8 with ram horn exhaust manifolds. The right side manifold has small little cracks at outside wall just below collector tube.
Question: Can these cracks be welded closed? or should I just junk it? They don't seem to go all the way through, but might expand when engine runs. Might is not the right word , they WILL expand, and tht's why I thinking welding may not work. But I'm not an expert.
