I was doing the !wire mod and it looks like a broke some kind of connecter, Im pretty sure it was pressurized so maybe oil pressure sensor? Heres some pics:

 

Looks like some sort of vacuum solenoid/diaphram. I dont recognize it so it must have something to do with emmitions, either AIR, EGR, or EVAP.

Are there any electrical conenctions going to it? Where does the other vacuum line on it go to?

 

Looks like some kind of one way valve in a vacuum system. Can you see where the other end is? It looks like it goes toward the passenger compartment. Is the other end pulling vacuum when the car is running? Without being able to see where it goes, and having little experience with 98-02 F body (i'm a first gen f body guy), I would say check your heater controls. I think most modern cars have the heater doors controled by vacuum, though I may be completely wrong. See if your heater controls are working ie switching from the dash to floor and defrosters etc.

 

That's a one way vacuum fitting; it holds vacuum for the A/C vent controls. They are available at most auto parts stores.

 

So it's bascially a check valve for the AC controls? Yeah AC is another thing i dont have lol.

 

 

I havent started the car as I didnt know if it was part of the pcv system..... so to replace it its just as simple as getting another 3 way connector like that one? That line goes to a cylinder shaped thing, next to the horn. It has a 2 nipple type fittings with only one of them connected, and that goes to the thing I broke. So its okay to run the car as long as the ac is off? Thanks for the fast replies guys.

 

Well shoot thats like $3. I cant imagine it being specific to anything but the nipple size and the direction its put on haha. You got lucky OP.

 

It "Y"s up right around that area.. One goes thru the firewall and the other goes to the back of the intake (if I remember correctly).. then its in the wireloom all the way to the front of the car.

 

Yep, the only issue you will have is the A/C vent controls won't work properly. As a temporary fix, you could put a piece of vacuum line in there to patch the leak while you get the new piece.

 

It IS the vaccum source for your mode doors in the dash. it auto defaults to defrost and floor. u just need to replace the hose that goes into the cab of the car...easier said than done

 

You guys know your **** lol. So piece with the broken tip is just as simple as swapping a new one? And what about connectors? I have a feeling the others will try to break when I swap it

 

Its a vacum piece that controls the vents. Mine broke on my car and my mechanic fixed it with another 1 off of a ford expedition he had llaying around lol. Just take it off a junnk car

 

It's very common for those small black plastic vacuum lines to break. Over time and with heat they get brittle. The line and end fittings are all available at most autoparts stores. The rubber end fittings slip right off the plastic line. Often times its easier to find rubber vacuum line to slip over the broken plastic line.

 

Hopefully your whole System is working, mine went out on my Car..

 

LOL yeah when my oil pressure sender broke and I had to pull the intake those broke on me too. I fixed em with heat shrink though. Heat shrink, super glue, and a lighter. Everything works fine too.
