There are two occasions when I have had bluish white smoke bellowing out of the rear end of my 900T 8v, once was intermittant and the other non stop. The non stop event was when the turbo went -at approx. 125k miles- and meant plumesof smoke enriched the habitat of all around when I accelerated from standstill ie traffic lights or when at speed. The other occasion, and this may be more relevant to your situation, happened just after I had had the car seviced. The new air filter went in very nicely. I bet that if you take your air filter out of its plastic cannister you will find that it will have some oil swishing around in the bottom of it. This oil gets there via the tube from the cylinder head- for some reason the best place for this overflow is the air intake. I rerouted this pipe so that the oil now dropsout of the bottom of the engine bay.Obviously it was too much for the mechanic to clean out this cannister prior to putting in the new air filter.The oil was being sucked up into the engine and burnt off -hence the blue/white plumes of smoke intermittantly bellowing out.I assume intermittantly because it is only under hard accaleration that enough demand- ie suction-is called for to draw this oil via the filter-which was saturated- and into the engine.It may be that this is your problem too. Hope this helps!
