i traced them down and 1 goes to the vacuum distribution chamber thing and the other goes to a hardline that goes across the engine to a hose and stops. what the hell does it go to??? i looked in the factory service manual and it doesnt show where it goes. its the first turbo towards the front of the motor.
o yeah i broke the nipple off thats y i ask. damn thing was plastic, i thought it was cast iron.

Good question, ill have a look on mine in the morning and try to let you know.

Good luck

Are you talking about these 2 hoses?

It's funny how the vacuum diagram doesn't mention where they go. Now I'm curious

These 2 hoses are directly under the airpump......if you have on

Off hand, I'm pretty sure that the smaller line goes to the oil injectors and the larger line runs to the oil filler neck.

The vacuum diagram shows the oil injectors to be plugged in between the solenoids in the front and the rats next.

yes the one on the right is the one i snapped off.
it goes to a hard line obviously which goes across the engine then it switches to a softline but i didnt have a clue what it hooks up to.

yes I believe one is for the oil injectors and the other is for the oil purge system throws extra oil back into the intake I think

btw I have an extra turbo inlet if you wanna buy it I can ship it thursday when I get home...just m me
Oh and i think youll be fine driving the car like that till then

well the car is down for quite awhile, i just needed to know where it goes to. someone needs to add that in the regular and simplified diagram for other idiots like myself that break them. i might end up pickin that up from u anyways. i appreciate everyones help on all the questions ive asked.

Flybye

You can see that I previously broke that nipple, too

I fixed it using that adhesive stuff that dries like cement and is sold in autoparts stores. Honestly, I have no clue exactly where it goes. I suppoed you COULD always just tee into the other line that is there.

teamstealth

one definitely goes to the OMP, because those need constant vaccum to operate, and if you hook them to the UIM, they only work when ur not in boost


the other one....i dont have a damned clue, lol

Flybye

See here you can see the oil injectors dissappear into the nest. and that other stupid line on the turbo inlet dissappearts into nothing

while we are on the subject of vacuum lines. there is a nipple on the lower part of the UIM that is aimed towards the firewall, its not shown in either vacuum diagram, where the hell does this go?

1 2 NV

oops i meant to say its on the lower part of the LIM, not the upper. its just above where the engine meets the LIM.

Flybye

The diagram shows the Pressure regulalator solenoid (for the fuel pressure regulator) connected to an area somewhere in the lower back of the LIM.

It might be that one. Haven't been back there in such a long time I can't remember

i found out wherre that hose goes to. it goes to the lower nipple on the oil filler neck. the neck is out of the car so i lost track of where the hell that **** went. ill have to keep searchin for that LIM nipple goes to.

1 2 NV

update. i searched and searched through the service manual. the nipple on the LIM goes to the FPR. but since the primary and secondary rails are out of the car i couldnt tell.

You can see from the vac diagram where one goes. The other one which is not shown DEFINITELY goes to the oil filler neck. This is why the primary tubocharger impeller wheel is always dirty with oil, hence the need for an oil catch can. Hope this helps you out mate.

Here's an updated vacuum diagram fron Wargasm's collection. It's got more lines plitted. You can clearly see that the small vacuum line goes to the oil injectors, as well as the wastegate/precontrol solenoids.

Better Vacuum Diagram

I know it's frustrating but nothing "dissapears" in the nest.

hahaha... that's what i have been asking the forum for that missing vac.line going no where... I found out myself where it goes!

If you have a cheap mod then you can look for a small steel punch hole. I just made a bigger hole and once u screw in there, use some high temp adhesive! Voila

some just cap the oil filler neck hoses... but dont know if its a good thing to cap the nipple you broke?

Cihuuy

damn dude... ur link is so small, cant see a damn thing!!

Oops.. sorry. That's the thumbnail.

Here's the big one.

sorry for bringing this back but
On my car there are two nipples as well. on thicker and another thiner. thiner one was pluged, i connected it to oil filler neck via oil catch can.

Thicker one was there but it was loose. This is the one gong to OMP right?

I've tightened it with clamps from both sides but I'm kinda frightened, could it cause OMP malfunction?

It doesnt go to the OMP, it goes to the pair of oil injectors on the rotor housings (that are fed by the OMP). There's no need for a clamp, the nipple is plastic and you can break it by tightening the clamp. It anything, use a zip tie, I wouldn't worry much about it.

However, IIRC the smaller nipple is for the oil injectors and the larger nipple is for the oil fill neck (or oil catch can) so I'd double check your hose routing to make sure. Doesnt matter if they're mixed up, just verify that you do indeed have the oil injectors hooked up.

beqa16v

Yes i used a zip tie, not a clamp.
On colored vacuum diagram left nipple (passenger side) goes to injectors. left one is thicker. on my car right one was capped, it was going nowhere. the hose from oil filler neck was pointed down so i decided that those two were ment to be togather.
