if you are running bio then its most likely the front seal on the ip,

just a note of caution, don't remove the drive plate without locking the pump at the timing position as the plate is not keyed to the shaft.

yes, you should fit all timing pins

Cheers mate just orderd a timing kit..Tony

you can remove the pump without removing the belt but as its contaminated with bio i would suggest its time for a new belt.

what are your plans for replacing the seal?

Not got any plans at the moment as I have never done a injector pump or timing belt, the nearest thing I have done is a headgasket so I will be doing some research over the weekend and my timing kit should arrive tomorrow hopefully...Tony

OK I have now got the IP out all I need to do is find some viton seals and some info on how to fit them or if anyone out there would fit them for me I am happy to pay....Thanks...Tony
Also if anyone knows where I can get the viton seals from could you let me know...Thanks.

Try phoning round specialist diesel engineers in the area, I went to one in Fife and they only wanted £20 for supplying and fitting the seal.

that's a good deal, i was quoted £65 just to re-time my pump.

Seals can be bought from diesel bob.

if you are going to do it your self make sure you lock the pump shaft at tdc before you remove the flange as its not keyed to the shaft.

is it a fly by wire pump? if it is you may not be able to lock the shaft as its not got the same locking bolt the manual pumps have so best to get it done professionally.

Just my luck it is a fly by wire. rung a few places today but no joy as yet

DTM in Bristol have been given good recommendations, give them a ring and see how much they would charge to do the whole job.
