I am getting really frustrated, so I figured I would search out the A body wizards to help me solve this problem. I cannot get my thermostat housing to stop leaking. It is weeping quite a bit around the seam where it joins the intake. I have tried two different types of gaskets, two gaskets along with gasket sealer, and then I just went back to one factory gasket. The housing and intake had been powder coated previously, but I stripped both down to bare metal. Changing this is obviously a constant mess-making endeavor. The underside of the housing has grooves that the thermostat seemingly sit in, but those grooves are obviously larger than the thermostat. Unfortunately, I don't have a pic of the underside of the housing to show what I am talking about. But this is what the intake and housing (mounted) looks like. Any advice on how to stop this leak once and for all would be greatly appreciated. Thanks.
