After Run Oil For OS 75
I have a new OS 75 4S mounted in a Piper Cub. Since the new design does not require an external crank case vent to atmosphere, how do you put after run oil in a fully cowled engine? Please don't tell me to take the cowling off.. Fred123[&:]

RE: After Run Oil For OS 75
We hope you mean the O.S. FS-70 Surpass engine or one of the variants. O.S. has no .75-size engine.
You would have to pull the tubing off of the crankcase vent to inject after-run oil into the crankcase to protect the bearings from the fuel residue that accumulates there.
