At least it's the housing that is getting eaten away. I just noticed coolant pooling on my Holley aluminum intake and took off the chrome thermostat housing. It looked like barnicles were inside my housing. Since the housing is steel and the manifold aluminum, guess what was eaten away. Yep my manifold. So instead of buying a new manifold I cleaned it with a file as flat as possible and used isopropyl alcohol to clean it. Then the JB weld went on to fill in the dips and valleys. I am actually waiting right now for the JB Weld to cure so I can file it all down flat. I already bought a new housing with a O-ring seal, so hopefully this fixes it. If not I guess I'll coat it in gasket sealer. I don't want to buy a new manifold since I am buying Vortec heads soon and will need a new manifold for those heads.
