I promise to subscribe on pay day, I think I owe it to the club now I keep asking questions.

 

Right, I finally have my car back after 5 weeks of waiting and a nice bill of over £1,000 in total. But I still have problems.

 

I have had the clutch master and slave cylinders replaced, and the line between them both. Now what I have is a strange hissing noise coming from the clutch when it's not in use, but when it's pressed down, the noise goes away. And the car is idling funny, sometimes cuts out.

 

After a brief search, I've gathered it could be the clutch booster system. And there is a way to resolve this by removing the vac pipe and blocking it? Is this safe to do and use the car? I don't think my bank balance can take much more lol.

 

Cheers, again.

although it wont cure the problem if you do it, it will bring the idle up if its leaking and you can still use the clutch have done it myself! (get paid up!;))

Yep sounds like the symptoms of a clutch booster leak which means air is leaking and effecting idle.

 

Yes you can block off the vac pipe Which is completely safe to do, no noise no air leak BUT you will have a very heavy clutch :( i hope you don't get stuck in traffic much coz it will p1ss you right off, i drove around with no booster for a few months and boy i was happy to have fitted a working one again. Lets just say my left leg is bigger than the right :D

 

 

You can try and find a used one but they are hard to come by coz peeps use these as part of a manual conversion kit. iirc Z1 sell used ones which is where i bought mine ( $80 i think) btw new are around £300 AHHHH. Hope this helps

Thanks for your quick responses chaps.

 

I'm rarely stuck in traffic - good old Cornish back roads to and from work.

 

I'll give it a try later on this afternoon and see what happens then! Thanks again for the quick responses!

Sorted that. Has cured the idle problem but the clutch was still hissing a bit. Will see what happens when I take her for a drive later!

Alright, I'm just going to be very cautious now, I don't wanna break the car as I've just got it on the road for the first day since buying it. So can I just double check now? lol

Which pipe should I be blocking off? I've currently blocked the pipe labeld 3, just before it joins 2.

 

Is that right? I know nothing about this sort of stuff.

 

Sorry I am a pain. :D

mine make that noise, i thought it was the clutch

thats the right pipe! seal her up good and tight!:smash:(:confused: Im going to check!)

Thank Jesus for that. It's got a hoofing great bolt in it and some good old insulation tape over it until I can get to a bit of silicone.

 

Cheers Dan!
