Were you careful to make sure the rings didnt move around on

the piston, off of the locating pins, as you were installing

the cylinder in question? :shrug:

did you check ring gap on both cylinders?

the piston rings are probably directional and you installed the low psi. cyl. rings upside down look for a mark toward the end gap this should face up
