Upon startup I get instant oil pressure as normal. After warm up and takeoff I fly for awhile and sometimes my oil pressure dips down to 20 briefly and goes back up to 40. This may happen several times but usually not when the engine is good and hot say 200f degrees. I'm using 20W50 Honda oil. I know that's a bit thick for winter but it averages 60f degrees around here. Any ideas? __________________ Pete Hell Paso, TX Model III SN 1000 (about 6th owner) 912 Grove -------- Pete Hell Paso, TX Kitfox III, 912ul, Grove Read this topic online here: http://forums.matronics.com/viewtopic.php?p=229261#229261 ________________________________ Message 2 _____________________________________ Time: 08:36:51 PM PST US Subject: RotaxEngines-List: Re: Erratic oil Pressure in 912 From: "Roger Lee" Hi Pete, Probably one of two things. It is either an oil pressure sender starting to go or my first choice is a partial or intermittent ground. -------- Roger Lee Tucson, Az.

Somewhere on this site I read the obvious to double check all electric connections especially the "grounds" and when doing this I noticed a "ground wire" that appeared to be attached at a point where there was paint and possibly not making a good consistent contact. I sanded off the paint to ensure I would have good metal to metal contact and I have not had the problem since (>40hrs). I can't be sure that was the problem, but again I've not experienced it since. I also believe I read that it is normal for the electronic gauge to show a little higher pressure at lower rpm's than at higher rpms (cruise) and I have noticed this as well. I have a Westberg Quad setup model 3AQ4-41mm. I'm no expert, but maybe this will help, Paul Perry KF IV 912UL Read this topic online here: http://forums.matronics.com/viewtopic.php?p=229293#229293 ------------------------------------------------------------------------------------- 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.
