Heater core coolant leaking externally?

So I recently replaced coolant pipes under intake manifold along with heater valve and heater hoses, now im having coolant dripping off from above the oil pan? By the sway bar its really hard to tell but seems like its coming from above somewhere Could this be the heater core drain? My old heater valve wasnt working and maybe prevented this leak? Im not sure if i should use stop leak to stop the heater valve from working like my old 1 or do some kind of bypass, The green stuff in the pictures are a uv dye i used to help me find the leak not green coolant lol, please help and thanks!!
