WTF! My car is freakin' finished. I have everything put back together (except for my boost controller...) and the engine is fully reassembled. Now. I have two things left that I don't know WHAT the **** to do with. Hopefully these pictures are good enough to see what I'm talking about. This first one here is of a coolant pipe of some sort. It leads down to the bottom of the engine, almost to where the rad is. A hose obviously fits on the end of this pipe, but I have no idea where it is to go. ******' Haynes doesn't even show the pipe in any diagrams. Here's the pic.

So I honestly don't know what to do with it. I thought it had something to do with my second piece here. Which is a bent hose that has a one way check valve at the end of it. Seen here:

wtf is that?! I have no idea! I had it with the rest of my turbocharger things. Like when I took apart the turbo, all those lines and everything, I put in one box. That's where I found it, but the turbo is fully bolted on and everything is groovy with that. What's going on?!

Any insight woud be TREMENDOUSLY appreciated. I've looked and looked, and can't see where these two things go. I have a feeling they're linked. By the way. The hose with the check valve (pic 2) has a scent of coolant, so that's why I thought they went together, but no. Help me out here guys... Get me back no the streets so I can go run 12 sec. 1/4 miles...

I believe the first thing goes to your BAC valve. I'm not sure about the second. Radiator overflow, maybe? I don't have my car handy or I would have went out and looked

Get that 10AE purring again!

The hose end of the second thing fits to the first thing. Then the nipple end of the second thing slids into the TID where the hole is.

Dont listen to the bac guy.

yup...saabguy is right. the next question is...what is it for!?!? it looks like it's pulling air from the stock TID. something emissions related? if so, since i have all my emmissions off the car, can i just plug it up and be done w/ it?

Non nipple side of B to nipple A, nipple side of B to TID

It's the discharge line for the crankcase and evaporative emission control system (charcoal canister, purge valve, etc). It connects between the metal line circled in the first picture and the TID. Make sure the check valve flows into the TID.

Evaporative Emission Control System
This line is used under full throttle conditions.
The purge control valve does the same thing under normal conditions. you maybe able to cap this line, just attach the check valve so you don't get any fumes.

jetfire76

ok...so air(or whatever) comes OUT of this hose? into the TID? can i just open vent it? does it HAVE to plugged back in? i ask since i have a different TID w/o any holes.

NZConvertible

Yes. It depends if you want the system to work properly. I left the same line on my 12AT unplugged for four years and never noticed anything come out of it. If you're going to leave it unplugged you might as well remove the rest of the system (purge valve, charcoal canister, lines, etc).

Kanaida

okay, so I have the home depot pvc tid... do I need to tap a new hole in one of my rubber cup links and then put that nipple into that hole to get in the intake track? I just went outside and looked at the old intake (that horribly flowing tube beneath the air box) and I can see where I'm sure that little nipple slides into... makes sense.
Or should I just cap the bad boy and say "fuh-get-aboutit"?

Thanks for the help too boys! That was great speed. Posted this morning, and now it's 12 midnight, and 8 replies. *Sniff* I love you guys.

by the way...

Electronics get finished tomorrow night. The car will be started for the first time since February tomorrow night aswell... I'm excited! Can't wait for all that black smoke (I'll be runnin' DAMN rich until I tune). Tuning will be early next week (monday or tuesday). OH YEAH!

bump.

whats goin' on fellas?

TonyTurboII

I would plumb it back in.

jimmyv13

I left that nipple open vented on my car, with no ill effects. I have removed all of the cannister related stuff, and I have a mini catch can for the two "crankcase vents", for lack of the proper term.

Dyre

You could either plumb it back in, or just let it hang out (with the one way valve attached)

I wouldn't just plug the hole though- That might cuase some pressure build up in the oil pan/crankcase.

NZConvertible

If the rest of the system's intact (purge valve, charcoal canister) then yes. It must be plugged in or nothing will work. You could do that, and then remove the purge valve and charcoal canister. The environmental impact is negligable compared to your exhaust anyway.

Kanaida

lol thank you very much for the input guys. I did plumb it back into the intake, just following my afm.

To see how things went after fully reassembling, refer to new thread.

the idea of these lines are to keep the engine from leaking and burning oil. Once the car is boosting, the only area which is under vacum is the area right before the compressor. Vacum is applied to that line, and then routed to various parts of the engine. Without these lines, "crankcase" atmospheric pressure will be the same as the outside temperature, and may allow oil to drip or burn.

That line shouldnt "dump" any air because I think its got a one way valve somewhere. If your car burns mad oil when boosting, this could be a problem area (but more likely turbo oil seals).
