Xantia LHM leak - How to locate.

Post by gadgetgricey »

Bit peeved about this, as I think I may have been ripped off.

Basic scanario is that the height corrector "stuck" on the Xantia about a month and a half ago. Was going on holiday in a couple of days so took it to a local Citroen Specialist to be repaired.
Rung me up to advise that it was sticking and that he coule lubricate it and that would resolve it. Fair does, go ahead. He also advised that the dog bone connector was a little loose and that I should get a replacement.

Picked it up and all seemed OK, but then I adjusted the height when changing the spheres that night and it "failed" again.

Went on holiday in the wife's car but rang to advise that the £90 fix had not worked, possibly just the dog bone had dropped off.

Any hoo took it back to him three weeks later for him to fit the new dog bone and the corrector was still sticking,,, and now the metal rod connecting from the anti roll bar to the dog bone, had snapped.
He was willing to fix it, but wanted to charge £200 for replacing with a good second hand height corrector.
Also there now seemed to be an LHM leak from somewhere, that had not happened before, but he said that was the overflow pipe????

Was not willing to pay the £200 as have another car I can use in the short/medium term until I can get the time to fix/replace.

Any hoo, got the car up on ramps today and noticed that the LHM did seem to be leaking from the passenger sides somewhere. (Not the height corrector). In the end just cleaned up the height corrector a lot and sprayed some white grease. Set the suspension to standard and then connected everything back up. 30 mins, all seems ok. Did not even use the replacement height corrector that I had sourced from on here.

Topped up the LHM and took the car for a ride round the block and everything seemed fine.

Gone back to the car tonight and there is now a pool of LHM under the car, seems to be starting to drop from somewhere on the passenger side., and the front suspension had dropped.

Started the car and after a brief wait the front rose as it should, but the STOP light did not extinguish, so has emptied all the LHM that I put in earlier.

I'll see if I can get the car back on the ramps tomorrow afternoon, but just wondered if there were any easy points to check first, or any useful tips /hints in tracing where the leak is starting from.

Sorry for the long ramble, just feel I have been :twisted: out of £90 and may have also caused another problem.

could be the anti sink valve leaking,
this is just below the edge of the hydraulic tank and towards the engine,

Can you get at it without removing the tank, and if not how easy is it to remove the tank.

(Best stock up on LHM :lol: )

Put a catch pan under the leak, and pour through a paint strainer back into the tank once sorted.

With all the antisink valves popping of late, I think changing mine must be well due... Does the rear ever leak?

No and its only started since I had the issue with the FHC. Just wondered if me driving (slowly) on the bump stops to the garage has built up too much pressure and that's whats blown the "o" ring.

Will try and have a look later.

Dave,

He may have just knocked off the height corrector leakage return pipe on the front subframe. It goes to a "Y" junction and it's very easy to knock out the pipe from it..

It'll leak a surprising amount of LHM from there too. It's an easy fix, just push the pipe back into the connector...

Confession Time.

LHM Leak was caused by me :oops:

After the car went to the garage the first time, he reported that the spheres were faulty, so I changed them with a good set I had.

Car then would not rise after this, so I assume the dog bone popped off when I dropped the car to the low setting.

When I finally reset the height corrector the fluid leak started. Turns out I had not fully seated the passenger sphere so was getting a nice trickle when it was under pressure.

Tightened it up and all sorted.

With these mechanical skills it does not bode well for DEX. :D :D , but its all a learning experience.

Thanks again
