    I didn't realise that the valve springs rotate during operation. Very interesting. Awesome video!!

    Pretty sure the valves themselves rotate - well on my old clunker they do...happy to be corrected by the more knowledgeable though...

    Vales and springs need to rotate, piston rings as well.

    There you go.. Thanks for that guys. Was it due to the speed of rotation/camera frame rate that the springs appeared to start rotating backwards at a certain RPM?
