doesnt look like the water pump...maybe head gasket. Mine looks just like that. I just did the head gasket and one side didnt seal between the coolant and outside of the engine. Doesnt bother me one bit but if its the stock gasket it may be going bad.
how high up does it go? Mine leaked from the top and ran down to the oil pan like that (same side) for a long time. if it starts from the top it most likely would be the timing cover gasket. you have two ports that go through the timing cover to the water pump on the top. I just changed mine out a few months ago. no more leaks. Pita to do but yourself but a 1000 dollars cheaper. Really not that bad but it was my first time. I must say this do not try and remove your oil pan. just undo the two small bolts on either side of the lip by the harmonic balancer.
just noticed its been a few weeks hope all is well with your problem
