I tend to have the same problem , i know that the x5's do swallow up oil i do not have a problem with that. my issue is from time to time in idle my '06 4.4 will guzzle up a heavy dose of white smoke and it takes me some accelerating to get the bulk of the smoke out. any ideas or any posts as to what might be able to help?

thanks

ps im very new to this forum but have very much enjoyed looking around
