do you have a piston ring pliers? if you install the rings improperly they can fail (stretch out to far)- if you don't gap the rings they could fail...

1. get a ring pliers and take them out 1 piston at a time and gap them with a small file and a feeler gauge

2. if it were me I'd get a new set of rings with the proper pliers and start over...
