When you replaced the water pump, did you use a hammer on the top of the water pump to remove from the timing cover? Or did you hit it from the bottom of the pump? The reason i ask and most people don't know this, is the timing cover only has 4 bolts holding the timing cover to the engine block and they are at the bottom of the cover. When you hit the water pump on the top of the pump, the force will cause the timing cover gasket to break loose and cause a leak. Have you replace the thermostat gasket yet? I would replace the t-stat gasket first and then recheck before thing about the timing cover. Adding to other leaks you could have, the corner of the intake manifold could be leaking too.
