Answers :

It appears that you have a blown headgasket, a failing water pump, or a cracked block.

There is also the possibility of a freeze plug failing & leaking there.

You can bypass the heater core until you are sure your engine problems are corrected so as not to damage it from excessive pressure.

You'll need to reassemble everything and pressure test the system instead of starting the engine, to see where the leaks are.

Good luck !
