Yes, They rotate, One complete rotation each 5 to 7 minutes. How do we know? By placing a thermocouple in the piston between the top and second compression ring. As the top compression rotates, the ring gap passes above the thermocouple which blows hot gas onto the thermocouple. The thermocouple registers a peak for each rotation of the ring. The time between peaks is the time it takes for the ring gap to make one complete revolution." Now this is my Bible for engines, Aircooled mind you for Aircraft, Low RPM, but the technoligy is the same. (taken out of the Sky Ranch Engineering Manual Page 240) “Do the Rings rotate?
