The oil rings only needed to be checked to ensure they were greater than 0.015 inches. The oil scraper ring does not need to be gapped. Once you have all the rings gapped to the correct settings for their assigned cylinder bore, weigh the set and record the value.
How do you know if your piston rings are bad?
Here is a list of the most common symptoms for bad piston rings:
