I would get some new copper washers before trying to strip down,
This is quiet a common problem on peugeots/citreons etc with the same engine

Good morning , i hope you read this before starting to sort your motor . You will require new nozzle washers & clamp bolts , as the bolts are torque to yield & single use only . I have seen a great deal of this type of problem especially on Mercedes Sprinters . It is not uncommon to end up reaming the injector bore & sealing face with a special stepped reamer to restore the flat faces required for a good seal . The blow by combustion gases can erode the cylinder head , BUT more often it is the injector that suffers damage & the reamer simply cuts away any carbon build up . I would also recommend using a long reach bottoming tap to clean the threaded hole the clamp bolt screws into , reason ? any dirt can affect how the bolt clamps the injector down . IF it cannot reach full depth , the injector does not seal fully & your problem will return . I would strongly suggest you coat the injector body with Febi 26712 Grease- Ceramic as it was designed for injector & glowplugs , nothing worse than trying to extract an seized in injector . Common rail diesels are not like older style engines , they are very very picky about corrrect injector nstallation . A fraction too loose & you get leaking gases , fraction too tight & the clamp bolt shears , maybe not straight away m but it wil fail .
Injector (clamping yoke) 1st Step: Torque to 4 Nm ( 3ft/Lb ) ! 2nd Step: Angle Tighten/rotate 45° very important you only tighten as the figures are very low Good luck & just be methodical

Just a bunch of random ideas:
- There's a leak somewhere, preventing the pressure build-up in the common rail. - The common rail pipe itself is empty, thus it needs a lot of cranking, before the HP pump fills it up and bleeds the air out of the system. - The feed line from the fuel tank may have an air inside and it can take some time before the fuel gets to the HP pump. Not sure, if the PSA engine uses a feed pump inside the tank, or the HP pumps sucks the fuel directly. |
