ive taken off my pipercross induction box and got myself a standard one with a vw air filter and then my car wouldnt start, and when it did it would just die, it runs now but i had to turn the idle srew thingy loads and its certainly not running smooth, the only thing thats missing is vacume hoses, heres some pics could anyone enlighten my as to what they go to and weather its whats causing the troublesome running

s anythign else likely to have been afected by this change like the timing or anything like that?
-
you must have left one of the vacuum hoses off...too much air is getting in. check all the hoses are secure and there are no leaks. you shouldnt have to adjust the screw by much (2-4 turns at most) to idle correctly (~950 rpm).
-
nah didnt take one off, because the pipercross didnt have any vacume hoses on it, that one on top of the airbox never had one on....
-
there was an airleak on that massive rubber thingy that clips to the top of the box, works fine now but my lovely gargle sound has gone, which is ok as i dont sound like a subaru now :smiley: plus it idles and responds alot better and ide say its goes a little... maybe not quicker but definatly easier,
anyone know where those vacume hoses go?
-
This any help? Basically look for a blanked off vacuum hose and connect it up!

hmm, no actually, that airbox is different from mine, mine hasa vacume thingy on the side of the bottom part.......
-
that bit just opens the warm air feed from the zaust manifold shroud, its a small solid plastic hose which joins between the top & bottom halves :)
-
oh right,well i dont need that one then, whats the one on top of the airbox for.......the metal one
-
according to the diagram its the 'Diaphragm pressure valve'
No idea what its for though :grin:

excuse me.... did i just read what that!!! there must be some mistake!!! you have no idea what something is for!!!!!!?????
holy crap, has hell frozen over!
:smiley:
-
'there are some things man was never meant to know' :grin:
-
whats the world coming too...? does anyone know what its for?
-
haha!! ok, it doesnt connect to anything!! it just really looks like it does, so everythings in place really, so why does my idle go up and down so much? mayve my C0?... does that sound right.....?
-
I must start off by saying ive just pulled myself up from the chair as i passed out for a few seconds after reading that rubjonny didnt know where a part of a 16v engine went!!
Har!bo, I had to get my exhaust gases (whatever the tech' terms are for it!!) adjusted when i put my airbox on. Go to your local garage (as long as they have a pipe that they shove up your exhaust....ooh er missus!!) and bung them a tenner and get them to alter it. It will run soooo much better. My idle went to s~it when i put my airbox on after the Pipercross. Glad you have noticed performance differance. Im so glad i got shot of the Pipercross. Have you sold it?
-
nah its sat in my porch, its covered in crap, its orange inside tho, but black outside, only thing i miss is the deep gargle it made, its more resonsive tho
-
oh right,well i dont need that one then.
Maybe not, but you need to make sure that the pipe connection that originally went to it is blocked off or you'll have a vac leak which will upset the running. :wink:
-
ah really? so should i block off the vacume one and the one where the thick hot air pipe would go???
-
just the upper one. Or you could just run a vacuum hose between em, wont hurt ;)
-
ey? the upper what? im confused now......
-
ah really? so should i block off the vacume one and the one where the thick hot air pipe would go???
You deffo need to block off the vac connection that would have fed to the side of the airbox (or reconnect it properly) I'm not sure where it comes from and can't check on mine for you cos it was sold on Sunday :cry:. You don't need to worry about blocking off where the the thick hot air pipe connects from the manifold; that just helps with engine 'warm up' in the winter. But you could get some ally tube from Halfords to reconnect it if you like, they do the right diameter but I cant remember what mm it is. If you want to do that you need to check that the cowl on the exhaust manifold is present to make the connection, they often rust badly and fall off!
-
The upper hose connection in your second picture needs to be blanked off, or simply joinn it to the connection below it with a length of vacuum hose.
-
the guy at vw breakers told me that nothing connects to that top one, that it isnt a vacume connection at all, just looks like one.....
-
Im affraid your man is wrong. It connects to the vacume pipe that comes off the back of the top inlet manifold on the back right. It connects to a little yellow round thing. This yellow round thing has a vac pipe coming off it which goes to the airbox and splits via a T and connects to both of your devices. Without it connected im pretty sure you get a poor idle and poor running.
-
This pic shows the bit im mean. Its part of the main vacum feed for the servo i think. Its circled in red, look close! :grin: If your still not sure i may have more pics. Just let me know.

-
ah i see, ill have a good look later then, :smiley:
-
right ok, ah ive found a blanked off thing but im stuck now, the only blanked off connection is one off two coming off the bottom of the part coming off the side of the inlet if that makes any sense? is that the one that connects to the top of the airbox or is everything in the wrong place?
-
ok so i thought i felt arty
in this work of art you can see my current set up, do i connect the two arrowed things together? is that what you mean? or is it set up wrong at the moment anyway?

I hope these 2 pics may help mate. Im not very good with running problems!! Anyway this is what i did to my vac hose

And the other bit...

When i put a K&N on i was left with a spare vacuum tube, just make sure none of them are open/unsealed. I assume there should be somewhere to plug it in on the standard airbox.... If not just make sure its sealed. I did similar to 16vGTIPaul but stuck a load of blutac down the tube as a bung then taped over it like that!
If it is sealed and you still have problems then hmmmmm.....
Isn't that mystery metal thing the brake vacuum thingy magjiggy or is that something else?
-
hangon im lost now, am i supposed to be sticking a vac pip on the metal thing on the airbox and then blanking off the other end? shouldnt it connect to something? i thought that pipe went to the inlet manifold?
-
that pipe he has blanked off is what connects to the spare hose thats blanked off on your 16v :)
-
ah lovely,
*adds finding a vacume pipe to my list of things to do to car*
