Xantia suspension leak help.

Post by ajw361 »

My xantia 110 hdi has for some while had a leak from the front suspension pressure regulator (where the front accumulator sphere attaches too). It has weeped for a couple of years but is now leaking badly. I have read you can take it apart and renew the o rings but really don't want to get involved in that as the car is in constant use and I know if I attempt it something will go wrong leaving the car off the road. Has anybody got a leak free regulator lying around? Thanks in advance for your help!

Is the leak from where the accumulator sphere mounts (curable with a new sphere seal, possibly) or from elsewhere on the regulator body?

No it doesn't look like it. It seems to be leaking from everywhere but there!

It seems to be leaking from the bracket where it attaches to the gearbox but surely that's just a bracket and lhm wouldn't leak from there?

Just had another look and when the accumulator clicks you can see the bracket that bolts into the end of it move and the lhm start to leak out. I have tried nipping it up but the movement is still there when it clicks?

The bracket where it attaches to the gearbox is just that, a bracket. LHM only enters and exits via, I think, three pipes. I may be wrong and it's only two, can't quite remember. I know for definite that the two pipes that are next to each other have seals. One seal is slightly larger than the other and if they are missing or have failed then LHM will leak out no matter how nipped up the unions are.

I wouldn't have thought that the bracket movement is normal. The pressure regulator is attached to the gearbox in three places. There is that bolt that goes into the end of the round bit and two studs. The piping brackets also mount on to the end of these two studs. The main fixing of the regulator is the studs so I wonder if it's worth checking to see it they're tightened up. If they do need tightening, I wonder if the movement has caused the pipes to fracture?

Mine leaked from the end where the plate to the gearbox is too. There's a seal in the end of the piston in the unit. Replaced the seal with help from this forum. It's not a bad job, drilling a little hole to get at the circlip worried me but it worked really well. As a temporary measure you can take the plate off and shove a seal in there, I did that for months, replacing the seal every few weeks!

I never saw movement at the bracket though...
