there is a solution that isn't visible. Here's what i did. I took the valve covers off, located the opening into the rebreather covers using an old filter i cut a piece from the old filter to fit the opening and carefully pressed it into place. I used some liquid silicon to make a seal around the edge. Now any splashed oil or crud is picked up by the piece of filter vapors go right through. Voila no oil and crud into the intake, vapors are recycled. Nothing visible!!!.
