Chris, this is what i have noticed so far. the dark stain in you picture.............and in your video.
In your video, there is times when the droplets on the exhaust valve, are being drown or suck back into the intake.
almost, like that area, is so dead that there is no fuel there at all, but fuel returns back into the intake at that point because of the low pressure.
The liquid is spinning of the exh valve,running around the side of the opening and then drop in right were the stain is.
I never did see the valve change heights but it was interesting to see the swirl on in exhaust valve turn cw and then would turn cc further in to the video.
