I had weeping heater hose lines from weak spring clamps. I also had a small split in the coolant line going to the IAC. Both of these caused dripping behind the engine. Plus I’ve also had a failed manifold gasket filling up the valley.

Or you could be like me and bypass the IAC altogether... not recommended for climates that see freezing weather.
