I still don't know what to do about this. E70 was doing but it's gone but now dealing with similar with my 4.8iS.

From Westlotorn I wanna believe it's not my VSS as I don't have any of the symptoms like he described when VSS fail.

I did change both CCV and corresponding hoses but still smoke slightly after extended idle ONLY. I'm due to do all my gaskets soon and if I'm gonna do the valve cover gaskets might as well do the VSS don't you guys think? So I don't have to do things twice?

Currently at 117k miles.
