My car was doing the normal puff puff at first start up a while ago. Just want to post this up cause I dropped about a cup of Marvel Mystery Oil down into the crank case and the cold start smoke totally stoped about 2 days later.

I actually didnt realize that the mmo solved this problem until I thought about it for a while. Good luck!

NO kidding??!?!?! I need to try this.. My 7 is a bug-killer when I start it up. YOu just put a cup of MMO in?

yes thats it. No guarantee's though. if you are smoking bad then its prolly something else. I was just smoking a little for maybe 5-10 seconds. didnt cloud the driveway or anything.
