in 912 / 914 Technical Questions
8 years ago
Not sure I'm on the right place for this but I thought I would share something. I have a cavalon gyrocopter with a 914 in it. It seems that I was blowing oil all over the tail fin in flight. But on the ground I could find no leak. I cleaned the engine compartment up and tried running it on the ground but no luck. Time and time again. It was only until I ran it up to about 4500 RPM that I discovered the O-ring on the turbo sump was leaking. Just FYI.
