could it be possible for only the exhaust side seal to be leaking just enough to produce smoke at idle......it is t3/to4e that came with the DG3 kit. only 5k on it...the compressor side is nice and clean, nothing in the ic pipe or filter side.....i hate to think that it is the motor because i had it on my old motor and was smoking, put it on this newer motor with only 60k on it....and it has been smoking at idle since day 2...car runs awesome besides that?
