Some white smoke or even a cloud is normal after the car sits for awhile. It should always clear up in a moment or two.

Replacing the AOS may or may not help this situation - for some owners it does help and for others it does not. If you decide to see if replacing the AOS will help, expect to pay $600-$800 for a indy mechanic to do the job. Dealer will be closer to $1000. The part itself is around $100. Many people have DIY'd it but its a PITA.

When the AOS actually fails, you'll know it. There will be a smoke screen that would make 007 proud and if you're out on the road, the size and density will literally stop the traffic behind you (as jotoole said, it can be somewhat embarrassing). Many owners will think that the engine blew up because the amount of smoke is huge.
