If the valve in your heater core is leaking, you should see coolant
in the passenger compartment. A good heater core should handle 40 to
50 psi. Your radiator cap is 12 to 15 psi, if working, should
protect the heater core. If you see bubbles in the expansion tank
you most likely have a head gasket or head leak. There is a product
called Thermagasket recommended to me by a mechanic friend who's
used it and says it works as far as repairing leaking head gaskets
and blocks. http://www.rxauto.com
It's an expensive (around $100) 2 part mix and you must follow the
directions. If you try it please report your results.
