OR intake valve guide leaking down through the intake tube into the
airbox???

OR...????

This is why a wise old grey-beard at the airport, upon hearing me bemoaning
the fact that I've got an oil drip AFTER installing an air/oil separator,
remarked: "There are over 100 places that can leak oil on an aircraft
engine. Your air/oil separator has addressed one of them -- and created
three more potential leaks..."
