I replaced the intake manifold gaskets, water pump, thermostat etc. I still have coolant leaking very badly. It looks like it is below the head gasket, kind of where the water pump housing attaches to the block. Is there a freeze out plu located here? Is there possibly a gasket behind housing? I appreciate your help. I am donatimng $2 but willing to upgrade if information cures this dang problem.

thanks

Yes, it could be a rusted out freeze plug. The only way you are going to find out is to pressure test the system and remove anything that is obstructing your view.
