Thanks for that info, i have tried moving the intake flap whilst the engine is running and it made no difference, the smoke is that bad you would think that neat diesel or oil were being poured into the exhaust when the engine is revved. There is also exhaust fumes coming from the drivers side front of the car, it comes up the side into the engine bay. I have a turbo on its way so will try that, further investigation will be required though.
