Hiya guys
Been workin on the mig all day flushin out the matrix etc.
elbow slipped & i broke a small plasic pipe
From the brake servo to the side of the plenum there is a black pipe. About a foot from the servo there is a small bell shaped adaptor in the pipe with a small branch off it. I snapped the branch off aarrgghh.

What is it??
Is it a dealer order part or a part a acc shop would stock?
Can I bodge it to get home??
Can the car be driven with it off??

soz for all the questions
ta for the help

Right....

its a vac T-piece....

I would insert a small screw in the hole to plug the vac leak and then check where that vac pipe goes.....if its the vac pipe on its own then it normlay goes to the air injection actuator mounted on the radiator.....if that is the case then ignore it for the time being.

Scrap yard? It's the non-return valve for the vacuum servo, there's 2 one of them has 2 braches off it & the other has 1. You can get them from the dealers as a seperate part. I know cos I did the same thing, they get brittle with age.
You'll need to sort it eventually.

EDIT Doh! beaten again .....

I just broke that bit myself! Have tried superglue. I would get a another but it is not clear how I would get it out of the servo pipe which looks really tight on both ends. Anybody know how to get it out without damaging the servo pipe?

You can not remove the one way valve (which is what the bulge is).

One other option, which works quite well, is to drill the hole out where the broken section is to the same size as the thin vac pipe (i.e. the type the runs all round the engine bay to the multirams).

Then rough up the plastic around this area with some wet and dry and insert a 1 inch section of vac pipe (there is normaly some slack in the small vac pipes so pick one and chop an inch off it) in to the hole with a small amount of super glue on the outside (you need to be sure you dont block the pipe) and then surround the outside of the joint with epoxy for good measure (and hence why the surface needs to be rough).

Once its all gone off, your repair is complete!

Spoken in the best panto voice ....... Oh Yes You can! I've done it.    
I broke one & got one from a car in the breakers where all that was left was the bit from the servo to the non-return & the valve itself - the rest presumably went with the engine   - and used that in my servo to manifod pipe. You just need a hot air gun *carefull* or lots of hot water. The valve will come out of the plastic tube without buggering up the tube. Besides if you were to go to Vauxhall & use their EPC (any other copies would be breach of copy right      ) you'll see that the pipe is sold by the length (metre?) and there are 3 different non returns that are available for different cars. No branch pipe - 1 branch pipe & 2 brach pipes.
Use your hairdyer hot air gun after to soften the pipe to make the seal again.

......(you need to be sure you dont block the pipe) and then surround the outside of the joint with epoxy for good measure (and hence why the surface needs to be rough).....

Neither "Double Bubble" nor Araldite wouldn't hold onto mine when i tried that .... hence above. It seemed to for a while but as the plastic has a greasy feel to it didn't seem able to hold for ever & I was back to square one.

The above is intended more as a bodge to get home   although I had one glued fine on the explod for 6 months!

Vx sell the valve seperately by the way so you can get them new!

How did you get the pipe to re-seal after softening it, surely it needed a clamp or similar to get it to make a good connection??

Someone have a pic of this so I can envisage what were talking about?? Is it part of the plenum?? Would a replacement plenum fix the problem??

No but, a replaceent brake servo pipe would

The plastic pipe presumably has some kind of memory & after softening wants to be a smooth tube again :-/. It was pretty secure when cooled & I've had no problems.

I visited Vx today and ordered a new valve for about £10 inc VAT (inc ABS discount). Then I set about getting the old one out by heating the pipe with a hardrier. It got pretty hot, but no dice.

So I took a hacksaw to the plastic body of teh valve and sawed it off and then smashed what was left inside the pipe with a hammer until all the bits dropped out. I then prised the connector out of the servo unit so I could do the the same to the other side.

I think with a bit of luck and maybe a couple of jubilee clips, the new one will fit back in to the existing pipe ends

A hair dryer wont get nearly hot enough......an electric paint stripper used VERY carefuly from a distance might work.....
