I think I may have a bad head gasket, or a bad intake gasket, not too sure. I tried browsing the forums, and didn't find too much.. anyway.
I have a 2000 F150 5.4L 4x4, last night the temp gauge started getting pretty high, never overheated, when I was driving the temp would get lower then at idle (makes since, more air flow).
I parked it and checked it this morning, coolant was bone dry. I put in some coolant, started it up and watched it. I am getting coolant coming out on the passenger side, above the valve cover, but below the injectors. It is right over cylinder 1. More gas I give it, the more coolant comes out.
I am thinking intake gasket, as if it was a head gasket, I would be having white smoke, among other issues.. anyone have any ideas or familiarity with this issue?
Just had our truck repaired today with a bad intake gasket. Appeared to be leaking from the cross over where it bolts to the intake. However, when they pulled the intake we had five out of eight plug wells full of coolant, but it didn't seem to be leaking that much.
To me it does not make any sense that it would be an intake gasket... But, like I have posted before though- I am new to the Triton world, and some engines do run coolant though the throttle body and the plenum. Im thinking engine manufacturers do that do the warm up gas mileage is better. Usually you can re-rout the lines to bypass the intake all together and it will even let the truck get cooler air. You will just have to let your truck warm up a little longer before driving for gas mileage. Anyways, run your coolant lines... maybe your thermostat is stuck and it forcing that water out on the housing or near by.
I had to replace the intake gasket on my 1998 4.6L. The truck wouldn't drive faster than 50mph and the when on a hill, the engine light came on. The truck didn't run hot. I pulled the intake and had water in the last cylinders. The gaskets are plastic and crack from heat. Put new plugs and wires and runs great now.

there is an aluminum crossover tube between the left and right sides. o-ring seal, not a gasket.. the plastic manifold groove failes over time. You need to pull the manifoldl to get the pipe off. You can either try to fix the manifold groove ( or fill), or just buy a new manifold.
