Alright, on the LIM, I have two places for a vacuum hose and i can't figure out which hose goes where. First place is on the drivers side, in other words, underneath the UIM. It's right in the middle pointing up. The other one is on the passengers side of the LIM at the bottom, two pipes run into one, and a hose goes on it. Which hoses are which?

there are three hoses that come out of the front of your dynamic chamber...one larger, and two smaller



I think one of those smaller ones leads to the vacuum nipple under the UIM that you speak of...the larger one leads to the oil metering lines (splits to 4), and the other smaller hose is short, and goes straight down to a metal vacuum hose



and I think the other goes to the split air pipe, leading from the main cat



my memory isn't the best, so someone else better speak up...

is this one you're talking about? in the lower left?

if so, that's the one that leads to the split air pipe, that comes off of the main cat

Oh, I think I disconnected that one when i gutted my cat. That explains alot. There's one more i'm not sure about. I'm about to upload a picture...

One more thing while we're at it. If i remove the AC&CV, what do I do about the big hose running to it, and the wires connected to it?

I think you do like the picture above...block it off.

http://nailsmasher.hypermart.net/000_0355.JPG Sorry the picture's so big. I'm in a hurry. Alright, above the intakes on the manifold, between all the hoses right in the middle, you'll notice one more little spot for a vacuum hose. Any ideas on that one?

Well, I see the picture up there, but there's a hose that runs to the valve, which if you remove the valve, there's nowhere for the hose to run. That's not near as urgent though.

I could be wrong, but I'm pretty sure that is one of the three that lead to the front of the throttle body or dynamic

chamber, somewhere in that area. Let me see if I can find a better explanation...

I'm at work, but I don't have much to do, so I'm gonna go run down to my car real quick and see.

The three that run up into the dynamic chamber are all still attached at the bottom. I'm thinking it might be this hose. http://nailsmasher.hypermart.net/picture1.jpg There are two hoses coming from the left there. One has a throttle cable in it, and the other one is unaccounted for. Can anyone just go look at their engine and tell me where that one leads?

that's your cruise control cable and hose...they lead to a black cylinder in the corner, right? if so, that's what it is

even if that were the hose you're thinking of, it would have to wrap all the way around the UIM, so that's not it.



if those 3 hoses are accounted for, where does the middle one lead? (they are lined up vertically on the dynamic chamber

right near the throttle body, right?)

and kudos to you for replacing the oil metering line without breaking another...I couldn't do that https://www.nopistons.com/forums/pub..._DIR#>/sad.png

Yup, dude, you were right. I thought it was accounted for, but last night a few of us were working on the car, and someone must've bumped it loose. One more thing. Where does that cruise control hose run to?

closest to the firewall, on the side of the LIM, or possibly on the lower UIM, there are 3 places for hoses, 2 of them are

already blocked off, one of which is angled upward



the other 2 are pointing toward the firewall, and the middle one should not be capped->that's where I put mine



I could be wrong on this, because I had 2 choices for this hose, and wasn't sure...the one I described just seemed to fit

better

and what was it that you were doing to take all this apart?

I was porting the intake and replacing my PD.
