Rough idle and White smoke

Guys: My 2002 F250, 7.3 motor has recently begin blowing white smoke and idling rough on start. Motor starts fine, just rough idle on occasion with the white smoke and strong rich diesel smell. I can rev the engine a time or two and it clears up and runs ok and smoke goes away. I have read a ton of forums on similar issues but there seems to be little consensus on what the cause is. I just changed the fuel filter so I am hoping that may help. Also, I have run some diesel treatment through the motor. No problems with power when running and the rough idle thing doesn't happen on every start up. Any ideas???
