Does the engine blow that much oil through the breather? or is the catch can also the air/oil seperator? john h mkIII titus, alabama ________________________________ Message 5 _____________________________________ Time: 05:57:37 AM PST US Subject: Kolb-List: Re: Kolb/Jabiru carb overflow From: "Thom Riddle" Chris, Glad you found the culprit! My rather small air/oil separator has one inlet and two outlets. The top outlet goes via flex hose directly overboard. The bottom outlet goes to a petcock and from there it also goes overboard. After every flight, I drain the several drops of the muck that collects in the bottom using the petcock. As long as I never let the separator fill up (drain after every flight), no oil or muck comes out of the upper outlet and the tail stays nice and clean. I add no more than a 1/2 pint or so of oil between 50 hour changes, so most of what comes out of the separator is oily water. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x32 Don't accept your dog's admiration as conclusive evidence that you are wonderful.
