No I pulled it apart and took them with me and just matched the sizes.Not so easy if u need the car to go get the o rings.Someone may be along to advise as to the sizes.

Such luck. I ordered the O-ring from Citroen today. It's £6+ exc. VAT!!!!!!

It is DIAM65x73 which presumably means 65mm. internal diameter and that it is 4mm. diameter rubber. Can't remember it being that thick.

I'll let you know if it cures my overnight starting hesitation problem.

Yay! Well, mine now runs very well but takes serious cranking to get going from rest.

So youv'e already changed your O-ring? Did you get yours from Citroen or manage to get one from elsewhere?

I think that would suggest that your glow plugs are dead or the glowplug relay is not doing its job.

It's quite strange because I am not sure it would even run that smooth if the GP or relay was not working as after the initial heating of the combustion cylinder, the relay switches off and then switches back on until engine temp reaches 60 degrees or accelerator pedal travel is more than 1/3rd of its total travel.

Is it very smoky when it finally starts and, if so, for how long?
