I have a crack on my driver side exhaust manifold, would a jb weld do the trick?

No and welding most manifolds is very difficult if not impossible to get to last. Go to a wrecking yard and get a new one.

JB Weld or bubble gum should do the trick. I prefer Bubblelicious, grape flavor.


I all seriousness, your manifold is cast metal so any type of welding will have a dramitically different expansion rate. Which will cause it to crack the first time it heats up.
