Hello -
I know lots of our IO-360s leak a little oil, and mine's not too bad at 5.5 hours/quart, but I wouldn't mind a few thoughts on where to start looking based on the attached photos.
It's been leaking about the same for the last 6 months (when I got it). I just got back from a long cross country this weekend and took these pictures today before cleaning it up. After any length flight, there is oil streaming back on both nose gear doors and it appears as if oil comes out from the panel just below/behind the oil cooler on the left side and streams back toward the wing root (where I also clean off oil).
I only keep it between 5.5 and 6 quarts, so I know it's not overfilled. I've had a mechanic look at it during the last oil change with nothing found.
Thoughts? Should I just not worry about it?
Thanks!
Drew
