Ford F-150 - 1997-2003 :: Coolant Dripping Down The Back Of Motor From Passenger Wheel Well

So, the other day, I went outside and there was a puddle under the truck. It had been sitting for a couple of days, IIRC, so I thought it was strange. It rained since then and the driveway was dry one day later, so I didn't give it much more thought at the time. Then the puddle appeared again. Went out with a flashlight this evening and looked around. I remember there was moisture in a couple of spark plug holes when I replaced them. Some of it was oil, but one was definitely watery. So, I am not surprised that there is a leak somewhere.

But what I do find strange is the location of some of the puddles, and where it drips from. I guess since the motor slopes down as it goes back, maybe the leak is really at the front and it's just running down the head next to the intake to drip from the back of the motor? There is water next to the intake manifold there, to support that theory. But there is a puddle on top of the intake around the #1 injector. How does it get there? My pressure tester is one of the old ones that attached to the radiator neck, so I'll have to find another way to pressurize the system to look? It doesn't seem to match up to descriptions I've seen of the crossover tube or the heater/water pump tube.
