>Any chance it's fuel coming from your carb due to flooding and not water from your breather?Absolutely none. Fuel drips onto the concrete evaporate almost instantly and these were definitely creating wet spots on the concrete. I put some on my finger and it was water. Of course, I also had prodigious amounts of "sweat" on the upper end of my carb and the intake runners close to it, so I know it was condensation, just not sure why it was coming out the crankcase breather.Walt, Ben, and others- thanks a million for the engine shutdown/restart tip. I can't wait to give it a try!Oscar ZunigaSan Antonio, TXmailto: taildrags@hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________Date: Mon, 19 Nov 2007 21:55:24 -0500

It is normal to get water vapor out of the breather. I don't know howcommon it is to get enough to cause drips, but it would certainly notsurprise me. We have all seen water dripping out of car tailpipes in coldweather. Water is a byproduct of combustion. Most of what comes out yourbreather is combustion blowby that gets past the rings.One of the reasons that you want to be sure that your oil gets up to atleast 212 degrees is to boil the water out of it. Keep in mind that is 212at some point in the oil flow. It is not necessarilly that hot where youroil temp probe is. That is also the reason that for engines in short termstorage the manufacturers recommend that you run them so often, not just fora few minutes, but until the oil temp gets to the operating range.Brian KrautEngineering Alternatives, Inc.www.engalt.com-----Original Message-----

Hi Oscar,Just a thought... I used to have two "lunchbox" Bendix mags on mine. They produceone heck of a spark and are nearly bullet proof. I really like them... whencold starting and when running. Once the coils in those things get warm theyhave a tendency to not throw quite as hot a spark. When running it's no bigdeal. When starting it seems to be a big deal. I almost always had the sameissue. On a cold start it was textbook. Fire up every time on the same blade.When restarting it when it was warm, it might go after a few blades or itmight be time for 'Continental Calisthenics', if you know what I mean. A coupleof guys at a strip where I normally get fuel would always come out to see me,hang out and talk while I was fueling up then suddenly disappear when I waslooking for a prop. Guess they already had their "aero" bics for the day. Anyway, my engine guy finally talked me into an impulse mag. I found an old Eisemannon ebay, bought it and he overhauled it for me. Now I have one BendixSF4RN and one Eisemann with an impulse. I now look like I know what I'm doing( some may question that though). Much better and I'll hang onto the otherBendix for a spare. Those Bendix's really are great mags, it's just when theyare warm, those coils don't throw quite as hot a spark and then the timing isn'tretarded to help you out either for starting.Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: drips from the breather

I get the drips too. Not what I like to see, but like Brian says, get it warmenough and it will burn off. BTW I always do the taste test. How else can yoube sure what it is?Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
