1128 code came up and i read up on aos.  checked the suction seal at oil filler.  so replaced the aos.  suction better and code went away.  but smoke is here now.  
it's a pain to DIY.  so i went to an indy i know personally.  only took him 30-45 mins.  but it would have taken me 2-3 hours.  difficult to do unless you have the right pliers and a lift.  still "do-able" though.
