Arrow towards exhaust.(The smaller valve pockets).

Put the top ring end gap opposite thrust side(wrist pin).

Space the oil ring rails opposite each other( one on each wrist pin side) or slightly of to the side of the compresion ring.

Make sure and double check the oil ring expander ends are Not Overlapped and Do Not line this up with one of the oil rail rings gaps.
