Does anyone know of a common fault with the exhaust manifold ? My son has just bought a 1.0 54 plate Lupo, tidy little car, runs well with a few minor issues I’m currently working through. The biggest problem is the exhaust is blowing and it appears to be at the manifold, I have replaced the exhaust to head gasket and exhaust to what would have been the pre cat, but it’s still leaking. I’m wondering now if there is a small crack in the manifold. Has anyone encountered such a problem, is this a common fault if so is there a specific place to look, thanks in advance
