Right, about a month ago my exhaust manifold tried to part company, well 2 of the studs did anyway, I replace the studs and fitted a new gasket, within 10 miles it was chuffing again, I have sourced a new manifold checked it for flatness, cleaned and fitted with another new gasket, first start up its chuffing again, I've been round the engine/manifold and can't seem to feel anything or see anything blowing but it sounds like a single port on the manifold is blowing, I can't feel anything on the injectors.
Is there anything common that can cause this that isn't obvious?!
