My TD5 once again seems to have air in the fuel system which is making it splutter when starting from cold. Strangely it seemed since i last did the injector seals in March and is only since changing the fuel filter a few weeks ago. No signs of a leak though!
The injector that is in No.3 cylinder has a fault with the rings on the washer sealing face of the injector. Previously the washer has held for 12-18 months before needing replacement. This time is seems to have potentially given up early. Therefore, i think i need to change the no.3 injector. Am i better to try and source a set of injectors from an unknown donor vehicle so all injectors have done a similar mileage? Can they be refurbished at all? I know i will need to track someone down with nanocom to reprogram them whether i change one or 5.

The injectors can be refurbed but I found it cost nearly as much as buying new ones from britcar (which are genuine ones) so I ended up just getting a new set from them. Ray

Cheers, so the question really then is: Can i swap out just my one damaged injector and leave the 4 remaining ones in which have done ~125k?
Sadly I cant afford the £1250 for a full new set! Cheers Steve 02' 110 TD5 Double Cab Rebuild Thread |

Cheers. The issue is with the actual metal around the base of the injector. Normally they have two concentric raised rings which crush into the washer. My faulty one has a large section of the inner ring totally missing and a small fault in the outer ring. Not sure how this has happened but has been like it since the first time i did the seals. Almost looks like porosity in the material although i doubt this would have been missed by Delphi's QA from new.
The mating face of the injector and the recess in the head were spotless when i reinstalled them previously. Thanks for the suggestion though!

if you do wire wheel them do not wire wheel the tip as this can damage the holes then it will need new nozzles.

Any other thoughts on me replacing just 1 injector (thus 4 will have done 125k) before i pull the trigger on a new one?
Thanks in advance, Steve 02' 110 TD5 Double Cab Rebuild Thread |
