with 0 compression it is most likely major. usually when you have a ring break only it will still have compression around 30 or so psi. With 0 i'd say not to good. take the head off lets see if the walls are to bad to just hone. if it needs a bore job you'd need to bore all to be same on balance of the motor. to bore them all and buy oversized piston kit for motor plus gasket set. it would be better to part out motor and buy BR's.
