Where does the CSI get the air from? I know it's the tube there right next to it, but where did that run to? I capped it off, but I'd like to know where it should have gone...

 

The Cold Start Injector is for fuel...not air, so i don't think that it gets air. The tubes right next to it are for the PCV system I think.

 

yeah, the place where it shoots the fuel is an open area in the base manifold.

 

I popped my csi out today (part of the 3.1 build/swap) and noticed that the tube there next to the injector goes right into the passage that the injector shoots the fuel.

Is that part of the PCV system?

Anyone have a diagram of the PCV system? I really should have paid better attention before just yanking all those tubes out

 

for the 85 cars:

 

Any chance you've got a bigger pic of that you can email me?

I can't see anything in that one

 

I'll take a better one, that was when I still had teh bra on & 3.4 open manifolds was running seamlessly

Ok, so the tube (the one labeled 'to manifold inlet' - that should be the tube next to the csi I'm talking about)

Anywho, that tube runs into another tube that has the driver's side PCV valve, and runs to the charcoal canister, as well as to the tube next to the IAC?

Can anyone verify/disprove this?

What i really need, is a pic of the piping in the car. : /

 

I'm pretty sure teh tube beside teh csi goes either to teh pcv or the brake booster. I didnt really check tonight.

 

The brake booster hose goes from the booster, straight to the 'T' on the back of the upper plenum.

Anyone have a picture of the PCV system? I found a couple of my old pics, but they only show that the hose from the tube next to the IAC goes down under the upper intake. I really need to see the pipe that comes off the driver's side PCV valve, and see where it goes.

 

My drivers side PVC pipe goes to the back of the very lower intake. Angles out to the drivers side.

This a 3.1l

 

Wow.. Guess it never occured to me, to LOOK AT MY OWN HOOD.



Cripes I feel like a bleeding idiot.

Of course, I've got an excuse - I had to FIND my hood again

 

Doward, if you want i can take a pic of my 91 3.1 later tonight. Not sure if everything is the same though.

Let me know.
