I have to agree with others on headgasket. My 93 CSE had same symtoms, would go down 1/4" fluid in overflow when driving back & forth to work 20 miies total, then went to 1/2". Then it started overpressurizing the cap which only happened a couple of times before I had headgasket done as I didn't want to cause more cooling system damage (i.e. Heater core). Had a 1/16" x 1/2" hole in head gasket at water jacket indentation by #4 cylinder where headgaskets usually go bad. Don't think stop leak would fix. People in the past have not recommended using stop leak with the caveat of wanting to keep the car or not as it isn't a permanent fix. I think headgasket is overpressurizing your heater core thus why it is leaking now. If you drive it too much this way you may be replacing both headgasket & heater core, if not already.
