The air tube is fed from small holes in each exhaust port, so getting oil in there would mean oil is getting to your exhaust ports in your heads. If I had to guess I would say you have some bad valve seals on those heads.

Is there oil in your intake?....Make sure PCV valve is working ok...

Smokes on start up then goes away?...Then yeah, I'd guess valve seals possibly too
