I would expect when you replace the VDO unit, you will see higher oil pressure readings again, similar to original. I am now flying a Jabiru 2200A engine (still like the 912 just bought a different airplane with different engine). The Jabiru engine uses a similar VDO oil pressure sender and succumbs to the same problem over time. I have a mechanical oil pressure gauge as a back-up to check on the electric VDO reading. The mech gauge is currently reading about 5 psi more than the VDO sending unit gauge. http://sites.google.com/site/riddletr/a&pmechanix -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x32 War is a cowardly escape from the problems of peace. - Thomas Mann Read this topic online here: http://forums.matronics.com/viewtopic.php?p=298161#298161 ________________________________ Message 3 _____________________________________ Time: 03:54:10 AM PST US Subject: RotaxEngines-List: Re: 912 oil purge proceedure From: "Thom Riddle" Ross, On all the 912UL engines I've owned, the gradual reduction is oil pressure readings was due to the oil pressure sending unit slowly failing.

I would also recommend getting the new oil pressure cap screw, spring and oil pressure control cone. This takes ten minutes to install and many people have found that it steadies the pressure and increases it. This is the new addition for the 2000 hr.
