Tim, you're getting good help here from Jager, so I hesitate to interrupt.
I have seen oil (in small amounts) get to the air filter due to a bad aos, when combined with a poorly running engine.

Under normal conditions air only moves in one direction through the intake tube. However: if your engine "backfires", even just a slight stutter or a cough, then yes, you can see air moving the other direction, though only momentarily. I wouldn't worry about it at all, for the moment, as you could end up chasing squirrels that aren't there. I would focus first on your AOS, then on your vacuum leaks.

Then let us know how it goes.
