It was super nice and unseasonably warm out this weekend and I was on a roll working on my car stuff, so I bit the bullet and popped my pistons back in with the new oil rings and the original XFi gapless rings. Gasoline Fumes, let us know what you end up doing. I was staring at the rings for a while trying to figure out what orientation made sense. and I ended up putting the side with the straight cut across the width of the ring facing up because it has less surface area for combustion gas to enter that crevasse than the other kind of "L" shaped crevasse on the other side of the ring. You should know what I'm talking about if you're holding an XFi ring.
