Water leak AGAIN

Good morning!
I have another water leak in my Dodge Stratus. Yesterday I was driving and it started to overheat. I put water in it and it was okay, drove it again a couple of hours later and it overheated again. I waited a couple of hours and put more water in it but the water just leaked out again. I have had just about everything replaced on it. Water pump, timing belt, freeze plugs, thermostat, hoses, pvc valve. Praying that the engine block isn't cracked. There was also a knocking sound when I started it last night, I cut it off and left it alone after that. Does anyone know what it could possibly be??? :headshake

well the water could be leaking on the inside of the motor. and got down into motor breaking the oil down causing the knock..If the water is leaking on outside of the motor check back on the firewall the heater core lines are known for leaking. mine is as we speak hope to replace today.. good luck
