After driving my car one day I shut it off filled it with gas turned it back on started smoking terribly so I shut it off then back on after couple minutes barely any smoke. I remove my turbo there was oil in the xompresor housing now I also have my crank vent and pcv valve floating around not hooked up. Some people say turbo seals some say to much crank pressure. I'm going to do a compression test on it today see of its got low compression the cat only smokes at idle not while driving. Also the Turbo has no shaft play at all
