The crankcase vents into the air box, if you overfill your engine a bit with oil it can get pumped into the bottom of the air box.
I don't recall many people on here having trouble with valve stem oil seals.
Normally the sign for valve stem seals gone is a big puff of smoke from the exhaust when you open the throttle again after slowing for say a junction. Thats why I said get someone to follow you, I would get on a motorway or highway get the revs up to 7-8000rpm and cruise at that for half a mile or so (choose the appropriate gear for the speed limit). When approaching an exit shut the throttle and use engine braking to slow down to say 3000 rpm then grab a big handful of throttle. The person following may see wisps of smoke while the throttle is closed then a large puff as the throttle is opened.
