I was going through a quart of oil about every 9 - 10 hours. It seemed that it all ended up on the belly of my -4. I finally broke down and bought a Super Seperator from Anti Splat Aero. Once I got the leak at the "T" fixed that I installed in #3 cylinder head oil return everything seems to be working great. I also put on the vacuum valve to one of the exhausts which they claim to increase horse power. I have noticed about an extra 100 to 120 RPM. I have a Whirlwind ground adjustable propeller but I have not changed the pitch. I think I'll just throttle back and have the extra umph when I need it. Hope this is helpful to anyone considering such a move.
