Hi guys, had this problem for a while now.. my turbo started smoking on a long idle about 4-5 months ago..so i changed it for a replacement second hand unit and now this turbo also smokes a little bit on idle but more on overrun and then when i blip the throttle.. now this suggests turbo seals to me so im putting one on next couple of days to see if that sorts it.. any other things i could check or is it likely to be seals? ps there is no smoke on start up and car runs perfectly fine. cheers
