I have heard that if you twist a piston ring you can tell if it is bad.

cant remimber if it was supposed to bend or break..

any ideas?

Reusing piston rings is like reusing a condom.

So you will have to turn the piston ring inside/out ?

Yeah your going to get some blow-by ha ha.

not talking about reusing, just seeing if they were bad or not.

twist the ring 180 degree, obviously there is no sense in reusing.

Blow-by,scored cylinder walls, low compression, poor gas milage. Never heard of a test performed after tear down.
