Did you end up jb welding the hole? I bought this f150 truck recently and notice that there was a deal right above that area were a hose should have been connected so looked like whoever had it before rerouted the hoses so I put them back the way they were supposed to go and out came antifreeze from that hole you were talking about jb welding.. I have no idea what it is either.. Thinking about just rerouting the hoses back to were they were before which basically cuts off the water supply so that it doesn't come out of that hole/plug area.. If I were to guess it has something to do with the heater core why it's apart of the manifold I don't know..
