I have a 1984 Ford F-150 with a inline six with a 3 speed manual tranny. I just recently got the truck from my uncle and it needed some work to get it back running. My uncle purchased this truck from a guy who had blown the head gasket and he wanted to sell the truck besides fixing it. After I got the truck it already had all the gaskets to redo the head but I went ahead and sent to head off to a shop to reworked. I also had to replace the power steering gear box, radiator, belts, hoses, plugs wires and distributor cap, clucth master cylinder, and a new heater core. The truck runs find be it has a bad skip and has terrible gas mileage with a bad smelling exhaust. When my uncle finished the truck and didn't hook up and of the vacuum lines on the motor. So I have tried to hook up the vacuum lines that go from the EVP AIRB and the AIRD valves.

 

But when doing this I noticed that the AIRD was missing and it was broken off. I was woundering If anyone know of a place to buy the AIRD valve. I tried a few auto parts but noone can seem to find out what it is but I tried the ford dealership but they want $140 for the little valve. Also does anyone have the specs on how to hook up the vacuum lines a diagram.

 

I had to go to the junkyard for mine. As for where the vacuum lines go, I didn't have any luck with my '86, I ended up selling to get something that would pass emissions. Let me know if you've gotten any advancement done on that motor, I'll look around and see if I can find any diagrams.
