Re: Do rings rotate?
I see no reason as to why they would not rotate. They are not pined in place. The actual question in my opinion is how much do they rotate.
As for how come we care about spacing the gaps, we do know with 100% certainty the negative effects of a gap from the top on the piston down the side.
