Message Anyway, you mentioned earlier you pulled a valve out?

And yeah, black smoke is excess fuel in the mixture, blue is oil.

It does, however, look like its burning oil according to the CC.

Possible causes:

-Worn (or improperly gapped) oil control rings
-Valve stem seals (usually only smokes on start up)
-turbo oil seals
-bad PCV valve(s)
