ok put about 400 miles or so on the clutch and no for some reason last night it started to smoke. after the car warmed up it belched out smoke when i reved it. drove to my shop a little while ago and it was still smoking. (mild smoke not bad smoking. only smokes bad when i rev it.) i checked the plugs and they are perfectly fine. nice and dry. checked commpression. 108 110 121 112 no to good but not bad enough to be rings. then on my way home i figured if it was exuast shaft seal on the turbo then it would smoke worse when i step into throttle. so i did it a few times on the freeway and it boosted better then ever. 9 psi at 3k. then i pull into my house and it is not smoking anymore.
let it idle for about 5 mins and still no smoke. rev it just black smoke from being rich.
any clues.
