after having a good look at my CP rings, i cant figure which is the right way up,
the top ring and the 3 oil rings have no marking and dont look any different either way up, although the secong ring, pictured above, does, it has N2 stamped into one side, and a not tacken out of it the other,
also i just broke one of my second rings, so now where can i by a new one, single set or hopefully not a full set, as with all engine builds funds are becoming tighter by the day
cheers
