FEELING RAIL GAP
It can be very difficult to check end gap on oil ring rails or gapless ring rails. I opened up the gap on a top ring of the appropriate bore size and squared it in the cylinder with a tool made from a scrap sleeve. Just set the rails on the top ring and they’re square in the bore. Now it’s much easier to get a feeler gauge in for an accurate measure.
