Just wanted to mention that even with 12 quarts in the sump, there will be no oil residing in the accessory case where any of the geartrain is sitting in oil, even on tail dragger aircraft. None of the gears are exposed to any oil as part of the reservoir. These gears are lubricated by a couple of oil pressure ports for the idler gears and from oil that is pressurized and squeezes past the cam and crank bearing journals Jim, I note that you have a Rocket and therefore the engine will be operating nose-high on the ground. I'm not sure what effect that has, but it would put more oil in the gearcase. Also, as I recall, the Christen inverted system uses the oil reservoir as an oil separator with the crankcase vent line being plumbed into it and therefore I wold expect not much oil would remain with the blowby. Someone report essentially no oil out the breather with such a system. Not true? I'm certainly not an inverted system expert. Gary Previous post: I just finished the 40 hour test period and the engine is broken in as evidenced by the lower CHTs and EGTs. My first flight I started with 12 quarts, after shutdown, I had 8. The rest of it was apparently dumped as my rudder was covered in clean oil. Since then, it seems that anything over 8.5 qts or so, I loose it. I just find it odd that the dipstick calls for 12 quarts and I can't come close to that amount. I have heard from several others fellows now and the concensis seems to be, 8 quarts is ok.
