I have the same problem. The leak seems to be between the core and the plastic housing. My best guess is that the 2 seals (rubber O rings) between the plastic and core need replacing. The Bus Depot has them on back order. The question is how do you separate the side plastic cover from the heater core? It looks it is crimped on For the time being I removed the heater core. You can plug the rubber hoses with a bolt and put some clamps on it, or make a U shaped bypass out of copper pipe (double clamp it), or remove the rubber hoses in its entirely. This is what I did since I was doing a complete flush anyway. I replaced the T fitting under the Westfalia with a straight one.
