Our 2005 Honda Pilot with 180k has done this twice that I have noticed: Lots of oil smoke on start up. It then runs fine and does not really use any oil. At least that is noticeable.
It does not smoke while driving and seems to have normal power/etc.
In the old days it would have been valve stem seals as the #1 culprit. Given that its a more modern car (for me anyways) is there a different thing to check first like a vacuum sensor or PCV??
Any help appreciated!!
