    ......the intake manifold.

    As the repair of my car was nearing with the parts ordered from audi for the PCV breather hoses etc, i decided to be extra and do the N249 bypass as all the bits were out and the access was easy,

    In the ongoing war with the clamp clips or whatever you wana call them, this one was really awkward and would not come off, i got carried away with a pair of pliers without thinking and snapped the nipple off from under the manifold where the hose connects for the BOV!

    What on earth am i supposed to do now??? please help......... :ermm:

    i was thinking jb weld? or is there a way to block it so i don't need it?

    or... what if i flush it where its snapped and force a tight fit tubing into it?

    Hope i dont have to end up buying a manifold.

    im soo gutted!

    Mate, that's just unlucky, second mani's can be bought for about £40 if you look hard enough.

    id carefully file it flush then try and find a grommet that will fit in/over the hole and bond it into place

    where can i find a grommet with a nipple thingy on it? or will it work if i bond a rubber/metal grommet or washer onto the manifold then bond the pipe into that?

    If I were you, I'd get someone (or you) to put a blob of weld over it to blank it and pressure test it to make sure it doesn't leak.

    Then T into the pipe coming from the one nipple and use that one nipple for both feeds.

    Bobs your aunt - fixed. However, very important to make sure that the T you put in doesn't leak, s can affect the fuel pressure regulator, meaning less fuel than needed. Will be fine as long as it doesn't leak.

    Sounds like a genius plan mate!

    will it not restrict the work of the other hose? although its a braided hose il replace it with samco silicone hose, i think il seal the hole with jb weld or steel weld (cold welding that comes in two tubes to mix then apply)

    Atleast it will get me back on the road..... i didnt really want to go down the route of taking the manifold off and getting it thhreaded etc as iv had enough of DIY for now. just want it sorted and back on the road.

    Nope, will work just fine. It's boost pressure at the end of the day, it will just fill both hoses. Thats how a boost gauge works for example, you T into either the FPR pipe or the DV pipe and that works just fine, and causes no problems.

    thanks welly, and thanks for all replies, il see if i can find a female hose barb like this http://www.chicompany.net/images/Female_Hose_Stem_05b01-109.jpg and cold weld it over the hole in manifold and if not il just cold weld the hole shut and T off from the other hose.

    Hopefully car should be running great again tomorrow!

    cant wait and will keep the post updated

    I'm sure either way will be fine, although would be suspicious as to how well that hose barb would take, and how long it would stay on. Still, don't know until you try.

    ok guys, i got back from work like and anxious kid and got straight to the job, fitted all the new parts with jubilee clips and having liquid welded the hole where the nipple snapped off in the morning, i took time to do the job properly, all the bits are back on now, im missing one jubilee clip which i will have to get tomorrow and upon starting the engine there was no hunting in the idle etc, started up straight away and sounds fine,

    so.... cant wait till tomorrow now to get that clip on and take the car for a spin!

    N249 valve has been bypassed as well so looking forward to the difference,

    if it hisses again i will not be a happy bunny!

    Dude, i went with your brains this time as mine made the nipple break off lol

    Just took it for a test drive and im not sure with the results, hissing is still there in high gears and full throttle which leads me to suspect the BOV is dumping too quick!

    going to check it once engine has cooled down a bit

    You sure it's the DV? It could be a boost leak, higher gears produce a bigger request on the turbo for boost, especially when putting your foot down from 50 MPH in 5th/6th for example.

    What sort of DV are you running, stock or other?

    WELLY - we have cracked it! your brains and my cuts and scrapes, it was a split hose!!! the ones that comes from the BOV to the big Turbo pipe past the N249 Valve!!!! it was split under the jubilee clip and torn along the jubilee clip!

    cut it back a bit and screwed it back on took it for a spin and all sorted.......will update the boost leak thread now

    thanks mate!

    tbh id run a new vac line from the dv, back to the fuel pressure reg.

    put a t in and then run it to your remaining good nipple and then be a WINNER

    Sweet, certainly sounded like a boost leak problem.

    Glad you found that, let me know results tomorrow.

    Nice work :thumbsup:

    hi welly, took the car out on the open roads today and not much hissing at all, although i still suspect the DV is dumping boost as it lets off steam too early!

    need to find a nearby member and try their DV

    Hmmmm, any idea how old it is?

    In all seriousness, for the £30ish it will cost, I'd change it for another stock DV for testing purposes.

    To be fair, when they go, they tend to go completely. The idea is that the pressure from the inlet manifold forces (through the pipe to the top) the internals to stay shut. When you come off the throttle, there is a vacuum in the inlet manifold as the throttle body closes, which then sucks the DV open to release boost pressure. There isn't that much to go wrong with them.

    Get a new one for testing.

    ive got a fella coming down from chigwell after work tonight. he says his feels like its loosing boost and that if feels down on power

    for a laugh im going to gtech it before and after the work to see what can be gained in a couple hours and ill post back and let you know.

    his is an a3 aum. gonna go over the inlet system from start to finish then pressure test it all. ive only done servicing on his in the past (his is the one we found bits of broken dipstick tube in the oil pump pick up!) so i know its now in a good condition service wise, now were gonna start getting it completely up to scratch

    he is coming along on sunday to the drag racing thing so he wants as much of a chance as he can get against my tiny turbod mk4

    It should do, or at least be good enough for testing purposes.
