I don't recall seeing anywhere how many hours you have on your engine=2C but it can't be a tremendous amount. I'm just wondering how an area that is supposed to have zero (!!) moisture=2C is somehow getting so much. Maybe I'm not seeing the photos clearly=2C but that's what I see.

I'm not a fuel expert=2C or anything like that=2C but it jus t seems to me there is something you need to fix!! I'm curious......do you fill up your fuel tank(s) in your plane EVERY tim e you park it? According to what I heard once=2C you are supposed to fill u p your tanks after you fly the plane. Full tanks have very little room for a ir to deposit moisture on the inside walls of your fuel tank. Do you have a 'well placed' moisture trap?? I mean=2C one that does a gr eat job of letting ALL the water settle into it=2C and allows for easy and thor ough drainage. I think this is something you REALLY need to be confident of!!

Mike Welch Mike W/Gang: The corrosion seems to be on the crank case side of the pump, not the fuel side. The engine oil is probably not getting hot enough to cook off condensation, which collects where ever it can find a home, e.g., the cavity in the fuel pump and many other places inside the engine. I do not know about the Jabiru, but 912 engine oil must get at least 190F, during a flight, to be hot enough to burn off condensation. An easy check is remove the oil tank cap, after a flight, to see if there is a milky substance covering the bottom of the cap. If it is, it isn't running hot enough. For me, that much corrosion in the fuel pump would be cause to wonder about the rest of the engine.

And, since a high percentage of the combustion products is water vapor, it is not surprising to find it accumulating and condensing on things inside the crankcase. In most cases, if you can keep the crankcase and the parts in side it at or above 180 degrees F, most of the moisture will not condense inside the case and will blow on out the vent as vapor. Fortunately for us two strokers this is not much of problem as the crankcase is constantly purged with fresh air, fuel, and lubricant. Jack B.

You can see I'm no Jabiru fuel pump expert .. One thing I do know=2C tho=2C is that simply reaching 180-190 degrees F isn 't all there is to moisture in your crankcase. Once you've achieved a steady-state warm engine=2C let's say 190 F=2C you have to maintain that temperature long enough to do some good. How long? Well =2C that depends on a lot of factors=2C like engine design=2C ventilation=2C et c. The condensation is going to take a while to be able to 'escape' through a breather cap or v ent=2C or whatever. Just getting the engine to 190F and shutting it off=2C isn't going to eliminate moisture. In fact=2C it'll make it worse=2C because it is the co oling down effect that causes condensation. Seeing as how the moisture is a product of Chris's crankcase (and not his fuel delivery system)=2C then this would possibly be a characteristic of his fly ing conditions=2C or flying habits=2C wouldn't it? Possibly due to the cold=2C northern cli mate=2C or the duration of his flights=2C or maybe even the wrong thermostat for his conditions=2C clearly something needs to be remedied. Without a doubt=2C Chris needs to make his flights a lot longer=2C or cer tainly long enough to achieve a dryer moisture level inside his engine's crankcase..... 'cause what he has at the present is causing some risky landings!! Simple question=2C Chris=3B How long would you say your typical flight is? 15 minutes? 30?? Also=2C can you get a higher temp rated thermostat? This might help a lot.

You can see I'm no Jabiru fuel pump expert. One thing I do know, tho, is that simply reaching 180-190 degrees F isn't all there is to moisture in your crankcase. Mike Welch Mike W/Folks: I went back and looked at the new Owners Manual, 912 series engines: - Eng Oil Temp operating range 190 to 230F (This temp is read at the outlet end of the oil pump, but before it goes back through the engine. This is oil fresh from the oil cooler.) - The manual also states eng oil temp should attain at least 212F some time during flight each day. It does not explain if this is 212F at the eng oil temp sender on the aft end of the oil pump, or oil temp when blow by gases push the oil out the crankcase on its way to the oil tank after it has been heated inside the engine. My experience has worked out well using the old spec which was attain 190F during the flight. No time at or above that temp specified. If I comply with this, I have a nice clean oil tank cap on the inside. If I don't get the eng oil to 190F (indicated), I'll have the tale tell milky looking oil residue inside the cap. My experience has also been that condensation converts to steam well below the boiling point of 212F. I also know there is 3 to 5 psi crankcase pressure constantly purging the crankcase of steam/contaminents, pushing oil out of the crankcase and back to the oil tank. The condensation does not have to be boiled out of the crankcase. About the only way one could get the engine oil temp to 190F on the ground (912) would be bypass the eng oil cooler and tape up the radiator. Difficult to get 120F, as required, prior to going full throttle, especially when it is cold. Don't think it is the cooling down that causes condensation in the 912 engines, but the by product of combustion. There is a lot of water in the air, especially here in the SE. john h mkIII Titus, Alabama ________________________________ Message 15 ____________________________________ Time: 09:29:58 AM PST US From: "John Hauck" Subject: Re: Kolb-List: Re: Kolb/Jabiru carb overflow Attached is a photo of the Jabiru 2200 fuel pump from the Installation Manual. You can't see it in this photo but the fuel line FROM the pump to the carb is behind the supply line with the fire sleeve to the pump. -------- Thom Riddle Thom R/Folks: The way the pump is mounted, inverted and canted, seems to be a built in situation to trap condensation. The 912 eng driven fuel pump is a "run of the mill" Pierburg pump, about the same as used on the old Opels. It is a throwaway pump that can not be disassembled. It is mounted on the gearbox and driven off a lobe on the prop shaft. Maybe this location reduces the amount of condensation it is exposed to, maybe not. ;-) john h mkIII Titus, Alabama ________________________________ Message 16 ____________________________________ Time: 09:57:56 AM PST US Subject: Kolb-List: Re: Kolb/Jabiru carb overflow From: "Thom Riddle" My Jabiru engine has its fuel pump located as shown in the photo I posted. I have an oil breather "catch can" that I empty after each flight by opening the petcock in the catch can drain line. It always drains out several drops of muddy/wet looking oil/water muck. This air/oil separator must be catching most, if not all, of the moisture in the oil system because the oil dip stick never shows any signs of this excrement or condensation, nor is there any when I change the oil. On my pusher configuration, with the engine hanging out in the breeze, and me living in the north with mild summers, it does not need an oil cooler and therefore does not have one installed. I rarely if ever fly in winter so the oil temps always manage to get up to the 170F minimum (at return line to engine) specified by Jabiru, as long as I don't baby the engine during climb. I doubt seriously, that the oil temp would get up to minimum in this weather without closing down some of the air scoop, but I could be wrong, since the CHTs get up to normal in cold weather. 18F currently (Thursday 1PM) and still snowing... almost continuously since Tuesday around noon.

Don't think I could feed a 12 gph engine. ;-) john h mkIII Titus, Alabama ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kolb-list Browse Digests http://www.matronics.com/digest/kolb-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
