The dot or marking on each ring always faces up.

Oil piston ring orientation diagram. Work the opened ring down from the top of the piston to the oil groove. Install oil control rings. Push the rod and piston out through the top of the cylinder. Quick video on how to install piston rings.

Please note that all three mm or narrower oil rings regardless of brand work best with split. Using a proper ring installation tool open the oil ring just enough to allow the ring to go over the top diameter of the piston.

It is a good idea after installing all rings on the pistons to recheck each ring on each piston for correct installation. This will allow oil which has been scraped off the cylinder wall by the top oil ring rail to fl ow radially to the oil return holes. Rotate the oil ring support rail until antirotational locking detent falls between the opening at intersection of ring groove and wrist pin hole.
