Denny, are you sure? I'll have to hunt, but seems like a few years back a cut away engine was spun over with a view for the rings and the rings did slowly turn in the lands.
I wouldn't think they would. In fact, I would have bet good money they wouldn't.
I'll see if I can find that video some where.
Maybe some one else can chime in here that knows more than I do. Wouldn't take much to know more than I.
