I’ve had a Saf-Air M12175 quick drain in the oil tank for about seven years and have been happy with it. It started losing a small amount of oil recently so I replaced it last week with a new one. Went flying today and this one also appears to be leaking slightly judging by the oil streaks on the belly. It’s probably lost no more than a quarter cap full of oil, if that, in a 1.5hr flight. The oil appears to be coming from the outlet and not around the crush washer. Anybody else had any experience with these drains?
