The Ring Gap Questions thread makes me realize how little I know about rings. So I take it that the ring gap is the space between the two ends of the ring. How do you adjust? Aren’t the rings preformed?
If the job of the ring is to seal between the piston and the cylinder wall then doesn’t it have to have proper contact against the wall. In my mind the ring comes preformed to provide the proper tension against the cylinder wall to create a seal between the wall and the piston. Then you compress the ring into its groove in the piston to install the piston.
Also, don’t the rings each have a different name and purpose? My memory is a little fuzzy. Grade 9 auto shop class was a long time ago.
