b18a1 rings.

I helped a friend install rings on his b18 bored .20 over the other day. When he did two of the pistons he installed the second compression ring upside down. I know the rings has a top side with (top) on it and he had them switched. He did not realize this until the motor was fully assembled. We started it anyway and no smoke no nothing and it ran strong on the dyno 18psi. What I want to know is there going to be anything go wrong with it in the long run?

So I guess everyones like me dont know.

how did you not catch this until fully assembled?

We got to looking at the stock pistons and rings we had. I just happen to say something about the way you should install the rings then he realized that he put the middle rings upside down. Motors running strong and no smoke at all with 2,000 miles on it but I want to know about the longtivity of the rings? The only difference is the little grove on one side and smooth on the other barly noticable thats how he did this.
