Rings may or may not rotate based on a number of factors, but the most important one is the cylinder wall cross hatch angle and depth. if the cross hatch is at an improper angle, the rings may actually rotate rapidly, wearing out the rings and ring lands prematurely. Another problem with improper cross hatch angle is either too little or too much oil on the cylinder walls. The wrong angle can actually work like a pump and overwhelm the oil rings and scraper.
Something else to keep in mind, if the engine was assembled with the ring gaps staggered, there probably would NOT be a line from the ring not rotating unless it was at the very top of the bore. How many have pulled an engine apart and found that there is indeed a scratch in the cylinder wall that goes straight up and down. That's quite common because of a burr on the ring end. clearly that ring didn't rotate orthe scratch would be circular in nature.
food for thought att the very least.
When your not sure where to place the gaps, i believe all of the manufactures sell their rings with instructions. if you can't find the correct answer there, just go to the total seal website and look it up. I know that'll take a few minutes extra time, but at least you'll get the correct answer from the guys that actually make and test those darn things.
