Pistons with broken rings will move from side to side with pressure
applied on the top. Broken rings can be the result of detonation
(pinging) and/or excessive ring land wear.
Another note... If a head is removed on a high mileage car (150K + on a
Honda), oil consumption can be expected to increase (assuming that rings
are not replaced) due to block distortion when re-torquing the head.
This is a result of the old rings losing their seating characteristics.
Don't ask me why I know this (G).
