Working on fixing a major noise-issue with an '03 ZX2. Pulled the front heat-shield, and there's a huge crack between the 1/2 cylinders (counting from the left). You can feel the air blowing out the manifold, and there's a heat-singe, on the inside of the heat shield, that follows the line of the crack. Looks almost as if the manifold is going to come off in two pieces.
Did some searches, and this doesn't appear to be a common problem. Am I not searching correctly, or is a cracked exhaust manifold a common issue on the ZX2? Thanks!
