I've never heard of piston rings rotating. Kind of makes staggering the

I had a Chevy pickup years ago that I changed the rings on one cylinder twice.
(This was before I had enough money to do things right) All five grooves on the
piston rings would be in a vertical row letting the oil get by and smoke. The
machinest said that the one cylinder was way out of round and the rest were OK.
He said that the rings rotated on the pistons so I believed him. Before that I
wondered why a good mechanic cleaned the grooves and rotated the rings before
He installed them.

Now for the other side. I overhauled a 225 HP Johnson outboard (Never again,
Too many pieces) The piston rings have keepers on them to keep them from
rotating. The oil injection must keep them from scoring.

The terminology Stuck Ring. I wonder if that means Rotation or Stuck in the
ring land or groove?

Like I say I am an amateur and the only way that I have learned is by doing it
myself because I didn't have enough money to let someone else do it.

Could a lifter have stuck open or closed? Had one stick on a 172 and knocked a
hole in the rocker cover.
