Where do these go??

audi5000 · 06-03-2010, 01:24 PM

so i decided to swap the cam in last night.
in and out no problem.
torqued the head down and decided to call it a night.
that was probably a bad idea because when i woke up to finish making connections i was left with 3 hoses.

must have forgot it overnight or something?
anyways i searched all this afternoon.
checked and double checked the maunal.

couldnt find where they go!
so now i need your help
i believe 2 are vacuum and 1 is coolant

ill do my best to show you what im talking about.
if im leaving something out just ask.

an obvious one is coming off the valve cover.

another from the throttle body

and then this coolant coming from under, along the block.

keep in mind that this is not the original engine, so it has been played with.

also i looked into those 2 vacuum hoses and the one from the TB actually comes all the way around into the one from the VC. could that be?

one I know goes into the throttle body - the small narrow one for cooling. its hard to tell from the pics what you have going on there. I'd have to see it in person.

haha I like the broken oil dip stick

I had similar thing, that disconnected bend hose in pic#3 or (#4 shows it better) goes into the "Throttle Body" cooling, (there is 2 of them), I see from pic you got other already connected, so connect the second one.

Edit: If you have a leaky gasket there, you can just connect those hoses together without running them to "throttle body". ...that cooling is kinda useless.

hmm i think i already have one going to the TB. ill double check!

audi5000 · 06-03-2010, 05:43 PM

okay i found the one on the TB and started her up!!!!
thanks for the help!

now my only is when at an idle i give it gas, she tries to stall out or lag.
fuel maybe? ???

vacuum leak maybe, a hose that isnt connected in the right place, or cracked boot, etc...
Are all your electrical connectors in the right spots?

dmytro · 06-04-2010, 10:40 AM

From pics your Idle Control looks like it may be bad...whats that green electric tape? also it suppose to be positioned "HORIZONTALLY" not vertically and that hose made from electric tape thats just bad

. definitely not a German engineering

audi5000 · 06-04-2010, 10:49 AM

thats how it was when i purchased the car.
i have not had a chance to replace it yet.

but now i guess i should really do something about that
Thanks.

Oh and the tape was for marking it.

As far as I know, orientation of the idle control valve doesn't matter.

Is this delay in response to aggressively revving the engine, or gradually getting on the throttle? A stumble then rev indicates A/F mix out of whack - can't remember what indicates lean and what indicates rich. Could be other things too.

Check that you don't have vac leaks - intake boots, vac hoses, oil dipstick seal, oil filler seal, etc. Also, check that you've got the FPR vac line attached and no fuel is the vac line. Also, check that the spark plug wire sensor is properly attached (it's a hall sensor on one of the wires - wire 1?).

If problems persist, check that the various sensors on the engine are within spec.

sure looks like your crank case tube isnt seated, did you fix that already?

dmytro · 06-04-2010, 02:32 PM

Oh yeah I didn't even notice....the crankcase! Hose is definitely not original (ask me how I know) it goes under the manifold, on top of fuel rail and into the crankcase and its very tight in there.

wtf? under manifold, over fuel into crankcase? what hose?

The crankcase vent tube goes from the crankcase to the bottom of the intake manifold, the OP's isnt seated properly in the one pic.
the TB has hoses coming off the left side(when standing on diver side of the bay) 2 cooling hoses that just flow coolant around the vac line that connects in the middle and run from the rear of the engine through the TB to the thermostat housing.
that vac line runs from the TB to the valve cover vent.
2 vac lines come off the right side of the TB to the booster
and one from the bottom of the TB to the vapour cannister/collector.
One from the boot into the hose to the booster
one from the boot to the ICV then to the TB.
Airbox to AFM to boot.

A loose connection at any of these points or a bad gasket(intake mani gskt, TB gskt, valve cover gskt) will be a vaccum leak.

Theres a good question above though, does it bog down when you apply throttle or does it surge then bog down?

This is the one I was talking about part# 11 15 1 708 801
