Still not had chance for a good look, but a new symptom reared its head today.... Started her up and there was a huge plume of white fuel smelling smoke, So I'm guessing its a fuel problem! The sound of the engine also dropped as if an electric fan cut out.... don't know if thats relevant?
Do any of these symptoms sound like the inlet manifold gasket problem? What are the symptoms of that and is there a test or error codes that should show if its that?
