I found the PCV valve on 2004 expedition, however, how do you remove it?? i cant seem to get it out of the hose. it is removed out of the intake, just still has some sort of bracket or something holding it in the hose

yes, those brackets tend to weld on from exhaust heat and corrosion. TRY hard to get it off, no working room there but you do have to remove it to get the valve off and often there's little room for wrenches. They bolt it on the engine, then drop the engine in the truck.
