Mystery Oil leak... cont'd and long

AH!! you are sooo correct! The 1/4" hose that is dripping the oil is the
air box drain hose, which exits just ahead of the breather hose (much
larger). Sooo now the mystery gets mysterious! Oil on top of the air box
collects from "where ever" several hours after a flight, seeps into the
airbox then slowly drains out the drain hose???

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

OR...????

1/4" is a mighty small breather hose! Check to make sure it's correct!
Also, you might want to make sure the breather line is placed so that it
definitely and distinctly drains back towards the engine, with no low
spots to pool or collect oil in. If you get an oil "pocket" small
changes in temperature can cause the air in the crankcase to "puff" the
oil out of the low spot onto the floor, or wherever.

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..."
