you can tell by looking at the end seal of the LIM gasket that its either old and shot or like the other guys said super dirty. my guess would be old and shot. my LIM gasket was pretty bad and i wasnt getting any in the oil. looks like you removed the coolant elbows. if you want, clean the fricken crap outta the engine bay especially the area above your water pump, and then for 5 bucks get new coolant elbows. install ur tensioner and what not and see if the leaks happen again. but you gotta make sure you clean it really really good. use rags to soak it up and/or an air compressor to blow it all out. if the leak comes back in the lower area, i would think the water pump is leaking. if it comes back in that groove on you LIM, i would think you have a shot gasket.
