Hi all, lately, I've noticed my oil pressure doesn't hold steady at cruise rpm with my 80 HP 912 Rotax. It never goes real low or anything, but will go up or down as much as 15 lbs at the same rpm. I changed the oil pressure sensor yesterday, and had the same issue with the new electronic unit. Funny, but it will hold steady, and then shoot up and then come down back to where it was to start with. Ranges of pressure are from about 55 to 70 with the VDO unit, and 60 to 75 with the electronic sensor. I suppose I should run a mechanical gauge as a check, but both senders have shown the same thing, so I imagine the mechanical one will do the same thing. Any thoughts? Jim Chuk
