Xantia regulator LHM leak...
Hi again...
This car is proving more and more troublesome. Given up on air-con problem for now, but fixed door locking mechanism (lots and lots of WD40 sprayed into the gap around the electrical connector to the mechanism, and the motor came back to life after months of not moving at all).
Changed accumulator sphere yesterday to reduce ticking from 4 seconds to almost never, and no longer clicking every time the brake pedal is pressed. But noticed leaking LHM. Cleaned entire area meticulously and re-checked today. The leak is from the back of the regulator, opposite side to where the sphere screws in. There's a mounting plate with a single bolt attaching it to the back of the regulator and it's from between the back of the regulator body and the mounting plate that LHM is weeping out.
Anyone had this before, and is it repairable? If the plate is removed, the back of the regulator looks a solid casting, but in fact I can see a large circlip (without eyes, just a tubular ring) that appears impossible to remove, just inside. Any ideas please?

Hi James,
I had exactly this issue on my V6 after the rebuild.
I cracked it by removing the plate and inserting a thin, large diamater O ring under the plate. There is a groove for a very fat O ring there but nowhere (so far as I can see) is there an O ring listed for this position.
Touch-wood it has stemmed the flow (albeit minor). You may achieve the same result by putting a bit of low-strength thread lock or Hylomar on the thread of the plate securing stud as well.
I've seen loads of pressure regulators a little damp in this area.

Thanks both of you. Unfortunately I fly back to the UK tomorrow evening so may not have time to do anything about it at the moment, but as the leak is fairly minor I'm hoping it'll be okay.
The problem I just can't sort and is more pressing is the air-conditioning, and now the fast-idle. Bought a new fast-idle electrovalve as the original was open-circuit but it's made no difference to the air-con not working at idle. On top of that, even though temps are high here, when I started it the fast-idle was causing revs to go to 1050 or so. When I revved to a certain point, the solenoid opened and the vacuum pulled the fast idle cable. As soon as stopped revving, the solenoid closed and fast idle came back on. This was same with air-con switch on and off.
Had hoped once ECU detected solenoid was okay, it'd de-energise the relay that controls the air-con clutch and let the air-con come on at idle - assumed it turned fast-idle on when air-con was switched on ready for extra load...

Hi, I'm returning from very warm and sunny East coast of Spain to the more dreary North of Wales. All good things come to an end I suppose. Due to work I may not be over again until this time next year, so the leak may have to wait till then, just had too many things to do this visit. It's only a small drip, but it's leaving the drive spotty.
I read through the posts regarding this problem via the search, but don't quite understand where this seal goes. I gather the middle section needs compressing in, and then the snap ring can be pried out. I see that should release the inner cylindrical section, but not the 'end cap' I read of.
As for air-con problem, I think it may have to be entrusted to a Citroen garage here and hope that the cost doesn't spiral.

North Wales !!???
Weather here on anglesey has been AS GOOD as spain this week!!!
Were in North Wales, let me Guess, Wrexham side?? 8)
Dont the regulators leak after they have ran on FLAT accumilator spheres for too long?? I find this IS the case, and seems right after you say you changed your regulator from click a sec to click a min ....
Theres a post somewere about replacing the O ring inside the end of the regulator, but cannot remember if its on here or CX fourm, or XM fourm.. I think it involved a GS regulator, but all are simillar...
I found this on the S1 Xantia I got here, but in a different way.. The car has a Hydraflush run through it, then LHM put back in, and then the Pinion Valve started leaking!!
ALSO- after fitting 4 new spheres, the rear arms showed their weaknesses, and decided to lean in after looking fine on the old ones.. rear bearings done now.. and what a difference to the softness!!!

hi james and all
I found the way to replace the seal on a cz site??
It involved cutting a nick out of the edge which then allowed you to remove thr clip dead easy (it must be I did it ) will have a look to find the site, Will post address later if I find it!!!
So you have been having fun in Spain, afraid I'm stuck here in France having to put up with the sun and wine and the food and the fun, really suffering, it's the village fete this Sunday where they FORCE you to drink and eat all day long!!!!!!!

I'd be grateful to know more on this Stephen as I'd like to fix mine properly one day even though removing a pressure regulator from a V6 is a task and a half. If you can find the link, that'll be really good.
I checked mine this evening and the O ring bodge is holding up a treat.

if you look up a regulator for a BX on service citroen it shows a complete break down of the above and all its parts,
if it works here is the link
http://service.citroen.com/docpr/affich ... 3%20391610,
the new O ring is part 18 and part No. 96157735

Hi Malcolm,
Sadly, you cannot as you need to be logged in to see it.
The best way is to take a screenshot and compress and resize it and post it as a jpeg image.
I can't right now but I can later for you.
Here is one I did earlier as an example..
How's the finger?
