Intake Manifold Weep

[KenBolton]

I notice a minor coolant leak around the back half of the intake manifold on the passenger side. I torqued the bolts down, cleaned and dried the area but still have weeping. Is my assumption correct that leakage is also occurring inside the manifold and that the gasket needs to be replaced? It seems to be an aluminum manifold. Either way should the trueness be checked?
