not absolutely sure what you are referring too in the pic. And I don't immediately recognize the engine although I really only know the 2.9L
Looks like a bunch of missing vacuum lines, a broken off/taped up EGR pipe and at the bottom of the pic, if I were to take a guess, that brass looking hex with nothing in it looks like it could be a ECT (Engine Coolant Temperature) sensor, but with the distributor right there...it seems like it isn't a 2.9L so...I just dunno
