As Mick and others have seen first hand, if a ring land goes south it might not show symptoms right away, provided the piston stays together. There've been a couple on here that were apparently driven for quite a long time with a broken piston - the only symptoms were a slight increase in oil usage and some light exhaust smoking, and other than that the motors ran pretty well. It wasn't until they were talked into doing a leakdown test [which led to a teardown] that they finally discovered where the oil was going.
