<<As I understand it, the piston rings (except the oil ring) all tend to
rotate around the piston in operation because of the cross-hatching. This
apparently causes no problems.>>

walls?>>
I don't know and that is why the concerns. By yours and others advice, I
think pinning the rings is an obsolete idea. So, it is better to let them
rotate hoping they don't align eventually ? By the known installing
instructions it seems that they should stay on the initial position all the
time. It sounds like aligning the squirt holes of the pushrods in an upright
position, at installing, if they rotate all the time at working.
As somebody told many years ago.... each new answer lead me to two new
questions. Thanks a lot to all who shared their wise advice.
