Xantia - Anti sink valve O-ring leaking

Post by lancia58 »

Hi

This is a correction for my post about a leaking union. I fount out that it is the front anti sink valve that is located below the Doser. I detached it and found out the there is an O-ring that causes the leaking. Can this O-ring be bought from Citroen ?

The car is Citroen Xantia 2.0 16V automatic make year 2000

Thanks

citroen dont list the/an O ring specifically for the anti sink valve, but i think one of the two different O rings for the hydraulic pump are the correct dimensions,

part No.'s and dimensions below

4026 87
HYDRAULIC OIL O-RING SEAL
DIAM 16-TO 1,9
- DIESEL XU

£1.62 inc VAT each

4026 88
HYDRAULIC OIL O-RING SEAL
DIAM 19-TO 2,4
- DIESEL XU

£1.38 inc VAT each

i think you can only buy them in packs of 5
