The most common cause I have seen for water in the oil on engines like your V6 would be a leaking lower intake manifold gasket. I don't see how a serpentine belt or water pump could cause water in the oil unless the engine has overheated because of their failure. Check the repairpal estimator for the cost of and intake manifold gasket replacement.
