intake manifold
alright so here is the deal i needed to change my valve cover gaskets and so i pulled out my upper intakemanifold to get off the rockers. i changed the valve covers and the gasket that sits between the upper intake and the lower one. now i figured out where everything goes except for one cable.
there are two cables coming out of the front of the intake manifold, one is something like a fuel pressure something and the other loops around the back, i dont know where this connects to. it does not connect to the part where the power brakes goes. the steering connection comes from the back of the intake manifold.

RE: intake manifold
I dont know of any cables comming off the manifold. The only cables there are are the 2 throttle cables comming off the throttle body. One goes to the cruise control in the driver side fender and one goes to the foot pedal.

RE: intake manifold
I am out of town at the moment, but i found this picture:
its number two in the picture, in my case it connects to number 3 and loops all the way around, it has a one way valve attached to it. when i tried turning on the engine it made a sucking noise.
on a sidenote, the engine starts smoking out of the valve cover gaskets in about thirty seconds. i know that the rocker arms have been completely sealed so there must be a lot of pressure. could this be because of this hose not being connected?

It is a factory T. Both provide vacuum. It is split to keep the oil vapors from all going to the same intake port.
It hooks to the PCV valve in the lower intake in the center.

RE: intake manifold
actually im not sure if it is connected to a nut like #3,but just loops all the way around and has a hook it goes through at the back of the manifold. im pretty sure its not part of the vacuum tree as that is already full and the only component it got from the manifold was the power steering cable from the back. the brake booster comes directly from an area close to the brake fluid

RE: intake manifold
ok i figured it out!
it is the PCV like stated. now is there a filter i should change or would fixing it up just be ok?
also, would this be the cause of the smoke? i.e. this connection not being fixed?

RE: intake manifold
Did you replace the PVC valve while you were doing that?Also you may just have some oil around there that just needs to be burned off or cleaned off from when you took the old gasket out.
