Just finished another oil and filter change at just under 16K miles. Each time I change the oil, since new, I've checked the crankcase breather tube for fluid but the tube has been bone dry. Curious because my '99 Valk I/S had some ugly looking stuff drain out each time I checked it when I changed oil. Is this a normal thing on the Wing or do I have a tube disconnect somewhere and the stuff is draining out someplace else??
