Back in the 1950's Perfect circle piston ring company had a stovebolt six in their training facility with a quartz insert in a cylinder. It was possible to watch that one on a dyno when under load. With a timing light pointed at the window, it was possible to see the piston rings slowly rotate around the piston. So much for the idea that ring gaps MUST be spaced out at specific intervals when an engine is assembled! The gaps might line up occasionally, but not long enough to make any difference in the real world!
