You say piston pin lock rings, I am assuming you are talking about wrist pins. If so, they require a machined groove in the pistn skirt to function properly. Also the fit between the piston skirt ,wrist pin, and rod has to be precise. An engine that has pressed in wrist pins will not use locking rings.
