Ok I am in the process of taking off my acv. The question I have is about what to do about some vac lines. Well I have one that is going from the acv to my boost sensor I believe.(its mounted on the pass. side strut tower) What do I do with that? Just not have anything going to my boost sensor? Also, just cap off every other vac line? Thanks for any help and I did search first:

Hook up the boost sensor to the nipple that's on the LIM near where the LIM/UIM meet.

Scott 89t2

it says on my site to use the nipple under the BAC. your BOV might be hooked to that. if so you need to "T" it

That's the one I'm talking about, I tend to forget the stock BOV is hooked to it as I didn't have the stock bov installed when I ran all my vac lines.

Ryde _Or_Die

Well right now I have a "y" that goes from the side of the UIM, one to my boost gauge, and one to my BOV. Is there any other place to do hook my boost sensor up to? How about if I get another "y" somewhere between my BOV and boost sensor or something? Any negative effects from this or a better way to do it? Thanks.

Also, there is alot of oil coming from the right side hole where I took the ACV off of. Is this normal?

NZConvertible

Hell no, the pressure sensor is very important. Just tee it's line into the BOV line. Yep.

Umm...I know mine didn't....

Nor did mine. Probably from the turbo problems you were mentioning before blowing oil through?

Ryde _Or_Die

Ya, thats what I think too. My turbo had like an inch or more of oil sitting in the bottom of it.

About the vac system I setup. I have one hose coming from the side of the UIM. That goes to a Y. One side goes to my aftermarket boost gauge, the other to a T. On side goes to my stock boost sensor and the other to my BOV. Sound good?

SonicRaT

Yeah, sounds just fine.

Ryde _Or_Die

Oh, one more thing. If where your ACV was leaked pretty badly, what would be the results? How would it affect power/boost/idle? Thanks.

SonicRaT

Leaked what? If it's the oil, it's just going to make everything dirty and so forth, if it was a vac leak you had/have, it's going to cause a pain in the *** idle, power shouldn't be effected too much, depending on the size of the vac leak.

Ryde _Or_Die

Hmm..well I have a good sized leak right now. I took the ACV off and went to put my block off plate on that I ordered months ago. Only to see that I got the wrong plate. So i ghettoed a plate temporarily until the new one comes in but it does leak pretty badly. You can hear the air rushing out or in or whatever it does. I know my acv was leaking before too because I had the same leak and alot of lines weren't hooked up to it. I had some problems with power and ****. Like my car started to boost alot(more load) but it wasn't going anywhere.

I'm not sure what the cause of that was, but i know when I had bad vac leaks on my '89 TII (i had 4 really bad ones however) that I could hit 5psi or so and then the car would run into a brick wall, don't know if it's related or not, probably not, but *shrug* Don't have any RTV to seal it with?

Ryde _Or_Die

I do, but the metal I used is just too thin(didn't have anything else). I didn't wanna just make a mess since this is only temporary. My block off plate was shipped out yesterday and should be here by the end of the week anyways.

Well, I guess you'll just have to see. I've been trying to think of something that might explain your problem, but I've not had much luck yet.

Ryde _Or_Die

Ya, so have I. I really don't know though. I am going to check to be sure like one of spark plug wires didn't break or anything like that too. If I had an ignition problem, would it put more load on the car, making it boost more?

PraxRX7

Well I half-assed my Block-off plate too, and it was leaking air, the car wouldn't run right, idle, or anything...

and it was backfiring like an SOB.

So I re-sealed it and it has been fine since...

Ryde _Or_Die

Also, is there a limp mode the car goes into if like a code is thrown?

Scott 89t2

only if it's the OMP codes

Ryde _Or_Die

Hmm..makes me think. I was looking today while it was running and I could see like air bubbles in the oil metering lines(mine are brand new). Is this normal?

SonicRaT

It's happens once in a while, either the injectors let air through, or you're low on oil.

Ryde _Or_Die

Well I don't think my injectors have any leaks since I just replaced all the grommets and o-rings, but I am was like half a quart low on oil. Any way that has to do with oil in the ACV?

It could have been, when you had the bad turbo and were blowing oil through it. How often do you check?
