russj249 2 Posted December 21, 2011 Report Share Posted December 21, 2011 The pipe should go from that nipple, to another little nipple on the inlet manifold, vacuum side of the throttle body. It also is a kind of t tiece, and should come from the carbon canister purge valve by the air box if i remember correct Link to post Share on other sites
hawwy 0 Posted December 21, 2011 Author Report Share Posted December 21, 2011 . Can u see in picture above the nipple where theres a rusted bolt. Its like a pipe blocked off?

hawwy 0 Posted December 21, 2011 Author Report Share Posted December 21, 2011 So this is the pipe. Link : http://img850.imageshack.us/i/imagexfn.jpg/So where do the other 2 side of it go and what is the pipe called and where can i get hold of it? Link to post Share on other sites
russj249 2 Posted December 22, 2011 Report Share Posted December 22, 2011 That's everythin there yes, its a crank case breather valve, very common for splitting and making cars run terrible.As you look at it, you have the main breather.pipes, one end directly onto rocker cover, and the other end to the inlet manifold plastic bent pipe.The smaller vacuum lines, which there are 3 of, the middle one to the top of the crank case breather valve, the right to where yours has been blocked off with a rusty bolt, ans the left bit to the charcoal cannister purge valve on the left side of the engine bay by the airbox, it is a little blue valve with a 2 pin plug on.I havent got one on my car now as its turbo and all the pipework is different. Also means I might have that t piece pipe lying around somewhere, but I don't know where. Link to post Share on other sites
hawwy 0 Posted December 22, 2011 Author Report Share Posted December 22, 2011 Thank you so much mate for helping. So where would i be able to get the t piece type pipe?Cheers Link to post Share on other sites
russj249 2 Posted December 22, 2011 Report Share Posted December 22, 2011 I might have one in the garage.. I will have a look later. I removed it just because of the turbo being put on.. want me to try dig it out?Main dealers will get them too, or you could get a plastic t piece for like a boost gauge or something and some vacuum hose.. all stuff a local car shop would have. You could use a t piece from sceen washer pipes where it splits from 1 pipe into 2 for each nozzle Link to post Share on other sites
hawwy 0 Posted December 22, 2011 Author Report Share Posted December 22, 2011 Yes mate see if u can find it cheers Link to post Share on other sites
hawwy 0 Posted December 22, 2011 Author Report Share Posted December 22, 2011 i know this sounds wierd ,b ut do you know like you said to the left near airbox there a little blue connector cannister purge valve or something? i dont have that on my car? Link to post Share on other sites
hawwy 0 Posted December 22, 2011 Author Report Share Posted December 22, 2011 I dont have the purge valve nor the wiring for it. Well i think i may have the connecter for it . So if i buy a new purge valve then where woul i put it etc. no wonder that pipe is blocked off its because i dont even have the valve Link to post Share on other sites
hawwy 0 Posted December 22, 2011 Author Report Share Posted December 22, 2011 Actually i dont have the woring or connector for the purge vlave Link to post Share on other sites
hawwy 0 Posted December 22, 2011 Author Report Share Posted December 22, 2011 Btw thought i would metion its a mk2vr6. Should i just block off the other nipple likenone in first pic? Thats best i can do cant i? Link to post Share on other sites
russj249 2 Posted December 22, 2011 Report Share Posted December 22, 2011 Well if the purge valve isn't there, what does the pipe from the carbon canister go to? Also if the valve isn't connected it's not an issue, it is an issue however if you don't have it connected and it's plugged in.With my turbo, I left the purge valve connected, and just into the engine bay, when Stealth Racing remapped it, I was told if it was being left to vent to atmosphere, it needed to be unplugged. You will have a fault code for it but, it won't alter the fuelling for when it purges if you get me.If thats removed and disconnected then, just get a piece of pipe and put it from the inlet pipe (that has been blocked on yours) to the crankcase breather valve.So long as the EVAP purge valve is disconnected, it shouldn't be an issue.I would strongly recommend that you get the car onto VAG COM, and see what fault codes it flags up.

Thats best i can do cant i?Ahhh thats probably why then hahaJust put a new pipe from one to the other just remove the one that's been blocked off, and put a new pipe from there straight to that nipple on the top or the crankcase breather.

hawwy 0 Posted December 22, 2011 Author Report Share Posted December 22, 2011 So that the pipe off the rusty bolt one and put pipe there to nipple and my running issues will be sorted ?And cheers again for helpan cantthank ya enough ! Link to post Share on other sites
russj249 2 Posted December 22, 2011 Report Share Posted December 22, 2011 Possibly.. Lol can't guarantee, but if it's sucking air then it will throw fueling out. It's the simplest thing to start with. They do suffer with other problems such as leads, coil packs, air flow meters etc etc.I've never worked on a mk2 conversion, so not sure how you'd go about retrieving fault codes. There are a few people with conversions on here, so hopefully someone can help out.It's the simplest and easiest and cheapest thing to try, so just connect the 2 with a bit of pipe and see what happens.

hawwy 0 Posted December 22, 2011 Author Report Share Posted December 22, 2011 Yep wil grab hold of pipe tmrw. I just put new leads in yesterday and coil seems fine . When i rev it a bit keep it held in one place then it revs up and down itself Link to post Share on other sites
russj249 2 Posted December 22, 2011 Report Share Posted December 22, 2011 When you say it revs up and down, do you mean it does it on idle?As in if you hold revs at 2k it'll hold fine, then when you let your foot off the accelerator, the revs drop but start hunting?

hawwy 0 Posted December 22, 2011 Author Report Share Posted December 22, 2011 Well on idle sonetines it reva up and down. Most of the time when i hold it at about 2k revs it goes up and down when its held in place Link to post Share on other sites
russj249 2 Posted December 22, 2011 Report Share Posted December 22, 2011 Hmm does sound like an air leak, but can't rule out other things. Just double check there are no other splits in any pipes.. could also be a faulty idle control valve.. is it an obd1 or obd2 lump in your car? Link to post Share on other sites
hawwy 0 Posted December 22, 2011 Author Report Share Posted December 22, 2011 Obd2 mate Link to post Share on other sites
hawwy 0 Posted December 22, 2011 Author Report Share Posted December 22, 2011 Where best place to check for air leak Link to post Share on other sites
russj249 2 Posted December 22, 2011 Report Share Posted December 22, 2011 Ok, obd2 has the idle control built into the throttle body, so no worries about the idle control valve. Air leaks are a bit of a pain.. the main one is the actual crank case breather valve itself, and those connecting pipes. Bit of a tricky one really without looking.Has all of the obd2 loom been used, and has it retained its diagnostics port, I think you could do with getting it into a computer and scanning it for fault codes. without these codes, there no way of telling if there's a faulty sensor, and which one it could be.Fix that pipe to the breather valve, see what happens, and if it still does it you'll have to have it scanned, and then go from there.

hawwy 0 Posted December 22, 2011 Author Report Share Posted December 22, 2011 The crap thing is that i got a mk2 vr for a donar car and that was used and when i took the loom out thats when i realise it has no connector. Link to post Share on other sites
