Replace the heater water valve infront of the firewall and check that there is a vacuum from the manifold to open the valve. My valve was corroded and stick closed and the rubber hose had a crack so it was loosing vacuum. Heater flapper in mine is a bit lazy and I hear a clunk a minute or so after I make a change. Another job for another time. 🙂
