[Biturbos4] White smoke

The oil is going somewhere.  Probably a turbo seal.  =(

Oh, and I might get flamed... but 7K miles between oil changes is far too
long for a 2.7 biturbo.  Personally, I recommend (and use myself) 3K mile
synthetic oil changes for turbo engines... and 5K for normally aspirated.
Except my Z06.  With high oil temps on the track, it gets changed after
every event.
