My 86 900T started doing that, a little puff at first and it went away. However, after time the smoke just started coming more frequently, until it was a health hazzard. it was the turbo. It died. the seals were all rotted and oil was bloing into the system. You could be at the beginning of the same thing, after all the car is nearly twenty years old. My dealer said that the turbos usally start to go after ten.
