If I am not mistaken, Ford updated that 4.6L intake with one with an aluminum housing area where the thermostat goes. Is yours plastic?

the thermostat housing is Aluminum and the runner is also the leak looks like it is coming from where the runner where the thermostat is(drivers side) bolts to the intake ford dosnt show a gasket between the 2 only answer i get from ford is buy a intake (has to be some sort of seal or wouldnt need bolts). I have had it pressure tested and dosnt look like a cracked intake

There is no gasket there. You will have to replace the intake if it's leaking there.
