I know this is a constant question. not too long ago ive been blowing blue smoke. it started coming out more and more at stop lights. when i rev it and spool up the smoke will go away and burn clean. i use all synthetic but im hearing that maybe my ta-49 might need a rebuild. it only has 15000 on the turbo and 40 on rebuilt motor. last week the blue smoke barely came out. now its pouring out. i took off the intercooler. fond typical oil residue but no oil in or anywhere near the compressor housing. i have to remove the exhaust housing but will i be able to find anything with all that residue. oh ya the throttle body had no residue as well. alot of people are saying that it sounds like a turbo seal and that most likely oil is leaking in the exhaust housing and being burnt and so when i spool up the seal expands thus not burning as much. but as soon as it spools down .oil smoke just pours out. thanks in advance guys
