I have a leak under the thermostat housing. While taking off the housing I broke the top left bolt holding the housing. THEN broke a drill bit trying to tap it!! Had to put a keencert in the manifold. Bolt seems to thread & tighten fine but can't stop this leak. New gasket was put on with Indian Head. What did I do wrong?? How do I fix this?
