I guess the question is - "was it sucked in, or was it pushed in?".
If there's no water in the oil (good thing), then I doubt about the 
head gasket. Its  a two-way street.
But where could it get sucked in by vacuum?  Some evap thingy?  Turbo 
housing leak (gasp)?

Or, probably a stupid guess but worth mentioning - might it have leaked 
to the manifold and been sucked into the intake from the outside of the 
engine - in other words, "its just a leak?"

I'm thinking sucked in oil for two reasons - puff of smoke while 
"getting on it" is consistent, and oil up in the intake butterfly is 
consistent. So whether its via turbo plumbing, evap or sucking it up 
off the manifold and through the snorkel, its getting into the intake 
somehow. If true, and it may not be, this sorta rules out lower-end or 
head gasket stuff, which, I think, is good.

Keep up the detective work.
