I just replaced my Water pump and elbows (aluminum dorman ones). Hopefully this fixes my problem because I can't find a leak anywhere else.

Not sure if all of the white crusty stuff on the WP was burnt coolant. The bottom weep hole did look like it had been leaking (sorta?).
I replaced my elbows while I was in there with those aluminum ones. I was meticulous about cleaning the **** out of everything so that there were no leaks (hopefully). The back elbow, did look like it had a slight leak and the front elbow either broke when I was pulling it out or it had a big ass crack in it (intake end).
Other then a little bit of coolant still dripping from getting everywhere it should be good now, or at least I hope so ! I will be completely blown away if this mystery leak hasn't been solved.
