If the car smokes at idle, on overrun and when started first thing in a morning it could just be your valve stem oil seals, common problem and not expensive to replace. Basically the vacum created by the engine whilst the throttle is shut (ticking over/overrun) causes the thing to draw air in from anywhere it can and if that means pulling air through worn stem seals it will bring the oil with it into the combustion chamber. Also whilst the car is stood overnight the hot oil has time to seep past the seals to the top of the valves so the next time you start the engine it will burn it. Sounds like the oil is leaking onto the turbo, have a good look around mate.
