Does anyone who if a cast iron exhaust manifold can be welded. I have one that has a small crack in it.

Thanks,

Yes it can be welded, sort of. The easiest fix for a cast iron mani is JBweld.

yes it can be welded. You must preheat the metal before your attempt to weld it, use a nickel filler rod, and Heliarc only (tig), then post heat it, then bury the manifold in a bucket of sand so the manifold cools evenly....

Thanks
