What's ths and where does it connect? I just reassembled my engine. On the driver side there is a connector over rear third of the valve cover. It connects to a sensor that is held in place by a little slit on the intake. I small vacuum line appears to run from it and connects to the t in the pic. I'm just not sure where to connect the t. I'm guessing it was part of my air system but that's been gone for years. I'm holding the t in the pic.

The more I think about it. I didn't have this plugged off before I removed the heads to change the lifters, so can you guys think of anywhere else I would have had it connected. Im wondering why I didn't get a vaccum leak if I really jut had it open to air. My buddy was helping with the tear down so Im not sure.

The T should actually be behind the intake manifold. The top hose is the only line from the AIR system (and should subsequently be capped off). The other vacuum hose goes to the HVAC system (runs to the passenger side of the car) and needs to be hooked up to the T so that it can draw vacuum from the manifold to operate the mixing doors.

Ah... ok, I see now. That's not behind the intake; rather, you're saying it's along the side of the intake/above the valve cover. The only other vacuum lines I am aware of (sans the HVAC line and booster line) are for the AIR system. I don't know that I recall another T fitting anywhere, though.

The T fitting goes on the back of the intake and one side goes to the HVAC the other connecting to your AIR solenoid. The AIR mechenism is on the side of the intake above #5. You can plug the HVAC line coming from the passenger side behind the computer directly to the rear of the intake and delete the AIR.
