don't waste money and time welding or JB welding the exhaust manifold. it won't hold. Normal welding will probably not hold on the iron, and JB Weld will never be able to take all the shaking and Heat. You unfortunately are going to need a new manifold. The crack is probably Upstream of your primary oxygen sensor, correct? It's going to mess up your air fuel ratio and that's going to cause other problems for both emissions and engine operation. This is one of those situations where you can have to bite the bullet and buy the part.
