head gasket

In order for it to be blown does the metal ring have to be broken

I appreciate your help. This engine has never missed, had water in the oil, or steamed from the exhaust pipe. Three radiators started leaking in the exact same spot. When you feel the radiator up you have to put the cap on , otherwise a lot of the water is forced out. This will happen if the motor is cold or warm. The head gasket looks ruff but the rings arent broken. I cant see were water has been passing on the block or head but that realy dont say much. Do you think a cracked head is my problem?

The only thing done was a compression test. It showed two cylinders 5 lbs weaker than the rest. This is the first ive heard of a block check tho.

I was told that a blown head gasket is the only thing that would compress air into the radiator. Should've asked you FIRST!

Thank you lots for your help.
