Valve Spring “bounce” and Valve rotation video

THIS video is NOT an aircraft engine…it is about a truck diesel engine…and MOST of the video is of no interest to us as aircraft owners…. But a short portion of it is High-Speed video of valve and valve-spring actions while an engine is Running… and I found it fascinating.
Skip all the video except click to view it at 25 minutes…for about a minute or two of video if you’d like to imagine what happens inside the rocker-boxes of piston engines: (start at the 25 minute point):

Note: Looking at the rocker-arm movement in the video causes me to suspect the two examples are not running the same RPM…so I’m not certain it’s a valid comparison…. But, it’s an interesting view.
