Is my head cracked, or just blown head gasket?

Ronnie where did you see the leak? On the engine block, radiator, thermostat housing? You seen the bad leak by just feeling it without the engine running? Very seldom will you see a bad leak with a blown head gasket or even a cracked head. The crack usually happens on the inside of the casting between the cooling jackets and its often not that visible. If you have seen a bad leak it would help to see on which part of the engine did you see it....just my 2cents. Good luck and let us know.

You need to fill it and then locate the leak. It may just be a freeze plug.
