Blow by?Cracked ring?

Was getting a lot of blowby so I did a leakdown test today. Leaking 60% out of cylinder 4. Air was coming out of the valvecover fitting....? Whats the problem? Bent valve? or cracked ring...?

i don't think 60% leakage would cause by ring. samething like that happened to my friend's car.
