Well I keep going out in the garage and finding a puddle of antifreeze in my thermostat housing, and a big puddle in the valley of the airgap manifold. Manifold is new, thermostat and housing are new, put it together with permatex ultra gray. I think its seeping up around the threads of the bolts, but cant remember from when I put it together. Do the bolt holes go clear through into the water jacket? Anybody have one on the bench they could look at?
