I just picked up a used 4.0 for the 89 MJ for $350. Professionally rebuilt 25k miles ago. Looks like the exhaust header was welded once, and it's cracked pretty good again. Any recommendations on a replacement?
Can I use an exhaust manifold from a newer model? The newer HO ones are under $100, but the older Renix ones are all over $160. I'd almost rather try rewelding it again instead of shelling out that much.
From reading other threads and pictures, it looks like the later exhaust manifolds will bolt up if you use the right gasket, but there is no egr tube and the output points back about 45* angle instead of almost straight down.
