When I got back I went under the truck and saw that it was starting to leak again. It seems to be coming from behind the drivers side mount where it connects to the block. The liquid doesnt seem to be oil because its not oily and it dries leaving a residue(as you can kinda see in the bottom of the pic on my cross member) I am beginning to think it might be a freeze plug maybe? But that liquid doesnt look like its coolant, obviously, so I'm a little lost. Any help would be appreciated. I can say that it isn't coming from the oil dipstick tube, not coming from the head gasket area, valve cover gasket looks fine. And the oil filter area is clean and dry as well. Here's a pic of the leak
