    Okay so here is under the hood of my 72 Maverick. I'm trying to identify a few things:

    #1: What two hoses/lines go from the PCV valve?

    #2: What is this? AC? The hoses from the filterhead are all gone. I am about to replace all hoses. Should I replace this thing? It is awful looking inside because this car hasn't had hoses for forever.
    https://drive.google.com/open?id=0B6sjl6MESfMHOUUtakdGUW9YWVU

    #3: Is there a good place to find oil cap + breather/hose in cap? AutoZone doesn't know what the heck this is.
    Mine doesn't have a gasket and just wobbles around.

    #4: This wiring look fine? Ha.
    https://drive.google.com/open?id=0B6sjl6MESfMHa2pHRVdDS1lXa2c

    #5: What does this contraption do? It's not connected to anything, sits right under the carb, and looks like it is throttle related or trans... butttt I'm lost. It's the bar/arm on the right, leads right over the block and under the carb to nothing. It jiggles like it is spring loaded and ends with a little point with an O that looks to attach to something (maybe carb?) but can't see where it would go.

    #6: Is it okay that the thermostat plugs into the radiator like so?

    https://drive.google.com/open?id=0B6sjl6MESfMHOUUtakdGUW9YWVU

    #7: This exhaust/pipe flange goes to the... headers? I think. But it is a flimsy piece of metal that would come off and feels like it could just fall off and serves no real purpose in my opinion. What is this? Should I replace? I have a hose for it to connect to the breather but it is so loose, I wonder.

    Thanks for any help. I can't find the Haynes manual for this and tried finding a good under the hood guide but figured I'd let you all have some fun trivia to brush up on your skills :)

    Number 1 is a thermostatic valve. Not sure what it was used for,probably emissions. I wouldn't mess with it. Probably won't work anyway. Either way it's not pcv. Number 2 is a charcoal canister. Obviously it hasn't been used in quite some time. I'd remove it and Chuck it.

    Number 3 goes to the base of the air cleaner. Just wash it with solvent and dry it.

    #2. Charcoal canister takes gas fumes from top of tank, filters through charcoal and then gets sucked into air cleaner to be burned in engine as aopposed to released to atmosphere (pollution, wasting gas via fumes). You can see the black corrugated hose going over around my passenger side shock mount.

    #5. Kickdown linkage. When the accelerator is depressed past a certain point, the throttle lever will contact the kickdown lever, causing it to force the kickdown rod (driver's side of trans) down, causing the trans to downshift. Under normal driving use, the two never make contact.


    #7. This is a shroud that captures warm air from around the exhaust manifold and delivers it to the bottom of the air cleaner snorkel when cold ambient temperatures exist. The flow is controled by either a vacuum-operated or thermal-operated actuator/flap inside the snorkel. The shroud and snorkel are connected with a larger diameter version of the paper/aluminum corrugated stuff like the charcoal canister-to-air cleaner.

    Try eBay for a Used Chilton manual. There should be lots out there.

    Seems better to tag onto this than start a new thread. Does anyone have a picture showing the spring(s) on the kickdown rod for a 200 6-cyl? My sons car has no springs and I know there is supposed to be one or more. Looking at Melvin's they offer a "KICK DOWN CONTROL SHAFT SPRING", D1AZ7146 that I think goes at the transmission end of the lever.

    On the 200/C4 the kickdown return spring attaches to a small bracket held in place by one of the bellhousing bolts. The other end of the spring attaches to the bottom of the kickdown rod just ahead of where it is clipped onto the transmission lever. There is a small 1/8" hole drilled beside the larger hole that has the plastic bushing.

    I can take a picture of mine this evening when I get home if you need a picture.

    Thanks for the pic it helps a lot. I was thinking there was also a spring at the carb end but apparently not.
