it bolts to the back of the air pump.that last picture is a check valve the supplies air to the exhaust.looks like it's rotten,and probably leaks as well.some one here knows how what size bolt you need to cap it off.and yes before you ask it's not doing anything,remove it.unless you need it for smog checks,it could get costly to repair.

thanks, that answers it for me haha
i don't have any smog to worry about, and i was going to take it off because it is leaking and it's driving me insane.
should I try my luck at a junkyard? or try to find a way to seal that one up

ther is a lagre bolt that will screw in there.just can't remember what size.or you can thake the tube off and put it on backwards with new gaskets,and will seal off the hole.cut the tubes off to.

The thermactor threads are 5/8-11 UNC.
We usually put allen head set screws in there to block them off, or you can just go to your hardware store and get some 1" long bolts and use them. Put some locktite on them to prevent them from falling out.

It may not matter to some of y'all, but...to some of us...especially CA residents, it does.
D4AZ9A487A .. Exhaust Air Supply Check Valve.
E3TZ9B289G .. Air By-Pass Thermactor Valve Assy (Motorcraft CX938).
Y'all know of course that there's talk in Congress of initiating a nationwide YEARLY smog test.
Here in CA, 1976 and newer, if the vehicle doesn't pass a smog test, it CANNOT be registered.
There are no more waivers for parts that are no longer available. CA sez: Fix it, or park it.
And...if you do park it, park it so the rear license plate cannot be seen from the street, because...
If the plate has an expired yearly tag on it, the polizei can have the vehicle towed away. Nein scheiss!

Mass used to test all 84+ for smog on a dyno but now they only sniff OBDII. The inspector is supposed to check visually that all emission components are installed and operating and the MIL/check engine light is out.
One of the dumbest things the car companies ever did was install the air tubes into the cylinder heads. Its prone to failure and it has a minor effect on emissions vs adding air at the converter. I had to swap heads on a 350 that didn't have the holes for the tubes and just used the air tube to the converter. My sniffer test was slightly lower than the previous year.

FACT: All the automakers are REALLY in the parts biz, where over 75% of their real profits come from.
If parts last forever, no profits for automakers...it's as simple as that.
