Try checking the thermostat housing as well as the water pump shaft area. These are two additional places that have seals (water pump shaft) and gaskets (thermostat housing) that are prone to leak, especially under pressure. You may want to consider having a professional from YourMechanic come to your location to diagnose and inspect your cooling system for leaks.
