hi mate. Some documents showing as the piston rings oriantation, top ring gap look to piston pin 90 degree ( center of piston skirt ), some docs, top ring gaps parallel the piston pin. Whic one is correct. I think if prevent the touch to piston skirt to cylinder walls, then we need piston ring gap must be paralell to piston pin. Top compression and secon ring gaps parallel to piston pim both edges. can you please your comments.
