(Sacha) ________________________________ Message 1 _____________________________________ Time: 10:20:47 AM PST US From: D L Josephson Subject: RotaxEngines-List: Cylinder head coolant leak? I'm working on a 912ULS from a windstorm-damaged plane that I'm pulling out to put in a homebuilt. The engine sat on the airplane for about a year after the airframe was totaled. All logs OK, looks very well cared for. But, #2 cylinder had about 1/4 cup of coolant in it. Good thing no one tried to start the engine, it was hydro locked by that. The spark plugs had some rust on the electrodes. I haven't pulled the head off yet but assume the valves will be in trouble too. The other cyls look OK. Is this a commonly seen problem? I have to guess there is some corrosion or a crack between the coolant passage and the valve. There's no coolant in the oil. Suggestions?

Thanks Bill. I've been away from the hangar (and email) for a few days but I will check it this week. ________________________________ Message 3 _____________________________________ Time: 11:52:12 AM PST US Subject: Re: RotaxEngines-List: air entering fuel system on suction side - or is my Pierburg electrical pump broken? From: Sacha Bob thank you. I will check it this week. Hopefully I don't need a new pump.... > On Jun 22, 2014, at 19:52, "Bob Harrison" wrote: > > Have you checked the thimble filter in the Pierburg electrical pump? ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rotaxengines-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RotaxEngines-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/rotaxengines-list Browse Digests http://www.matronics.com/digest/rotaxengines-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.
