Hello again right been a long wait cast manifold arrived from Uk, and will pick up soon, due to easter coming up x5 going 'in' on 28th april....mechanic told me it can take up to 2 days and went on about the bolts not coming out etc....and needing to get a specialist to take action to remove, at the end of the day i will tell him just take the nuts off please and if they come off just replace with new nuts that come with manifold, if the existing nuts are too jammed or shear the bolt then well yes not much choice then long way round....also told him about the turbo boost being low and not kicking in until over 2000 revs and under load and he said it maybe the hose, but hey heard it from most gurus here that my symptoms of visible smoke in the engine bay from cold and in the that area is a cracked manifold....and cant be totally unrelated to the lack of boost at low revs due to not enough pressure from gases to spin turbo....ok wish me luck....thanks
