Which side of the engine is that, and near which cylinder #?

The only coolant drain plug I'm aware of is on the block beneath the freeze plug at #8. That pic is of a cylinder head, and since water doesn't generally run upward I would suspect that it's peaking from the intake manifold (cracked manifold or bad gasket) and running down to wherever you snapped that pic from.

The pic isn't helping.
First, you need to rule out a bad intake manifold.Look for antifreeze in the block valley,and look for a leak from the rear heater hose connection to it..The manifold is by far the most common leak source.
