Fellow Rotatary Listers,

   Doug Loheim ask me about my return line for my RD1C gearbox, and if I had drilled the rotor housing yet. I have not, and I told him that I was torn between drilling the housing, or using the opening in the Renesis pan that contained a low oil sensor. If I drill the housing, the oil will be returned to the top side of the engine mount plate, and allow for the oil to settle back down before returning to the pan. Using the sensor hole in the oil pan, the oil will obviously be returned directly. My question is, how much air will be in the oil after the gearbox. Will it be pretty clean, or will it be frothy and full of air? Any thoughts?? Ed, Tracy, anyone else with lots of wisdom on the subject?? Thoughts???

Thank you in advance.

Ben
