Crap, may have to pull my pistons out

Had no idea the sealed power secondary rings are tapered. How do I know which is top and which is bottom?

Re: Crap, may have to pull my pistons out

I really need some help on this one folks....=/

I just noticed today that the rings have two colors on each end of the gaps, red and green. How can I tell if a ring is upside down? Im just happy I caught this because I still don't have anything on the block except the rotating assembly. Better to fix it now than after its in the car. Help please, thanks.

one side will be a 90 degree edge and one edge will be cut.

i think this is what your talking about, could be wrong though.

on the inside of the ring one edge will be square, and the other edge will be back-cut(slanted). on the top ring, the back cut goes down. on the 2nd ring, the back cut side of the ring goes up
