Does the loud noise sound like it might be blower motor related? I can't really think of anything else that would make a loud noise. Of maybe an actuator / door that directs the hot or cold air sticking and making noise as it tries to move?

Cracked head, or cracked head gasket? There's a big difference and a failed gasket is not usually referred to as being "cracked" which makes me wonder. Be sure to get a repair estimate before going ahead. This could start to run into some serious money.
