Piston Ring end gap
TBolt USA Tech Database!


Check for Proper Ring End Gap
Normally new rings will be fine , but just to be sure.
Failure to ensure proper ring end gap may cause engine damage
Your looking to have a minimum clearance so the rings ends are not touching 

Check the end gap by placing the ring into the cylinder
Use the piston to square up the ring in the bore
Check the end gap by using a feeler gage.

Your basic rule is 0.004" per I.0"  of bore diameter
