    refurbished injectors PSA DV6

    Hi all,

    It's been a while, but I am looking for some addresses, where I could find some refurbished injectors for the DV6.
    My father in law is in need of 4 new ones so we're looking for the cheapest ones tbh.

    Thanks in advance.

    What horsepower is the engine. I believe they are different between the 90&110.

    These injectors are not "refurbishable", they just aren't. Removal often f*cks them and the clamp bolts torque is critical to them working properly.

    DO NOT touch the tips or be tempted to clean them in any way.

    The only ones you should consider are brand new genuine PSA, and certainly nothing from ECP.

    Yes 90 & 110 are different part no's , and they will need coding to the ECU.

    I'm sorry but these injectors are 're buildable, coz I've personal had them done, they can be a complete pain in the arse to remove, but that's usual if the copper washers gone, if there stuck ur best bet will be to call a professional injector remover guy, they have the tools for the job and will have them out in no time, and they'll come to ur house. Then just send them off to a diesel specialist of ur choice, I personaly use diesel bob for mine, he's a very knowledgeable bloke and will help you out if you ring him, just search for him on google, and yes there is a difference between the 110 and 90, are you in a rush for the injectors?

    Well the guy that was working on my father in laws car couldn't get 2 of the injectors out, eventually ended up taking the head off and still did not manage to get them out...
    He ended up buying a second hand engine and will donate his orinal one to me to play around with...
    I knew they were refurbishable as I've read about plenty of people changing nozzles on them...

    Thanks for the help guys.

    Firstly the delphi and siemens *piezo* injectors are not properly refurbishable, and I do not care what anyone says on the matter nor whether new nozzles are available or not. In doing so you redically alter the flow rate and render the coding calibration completely; the engine will never run smoothly again as the the calibration is now wrong. The rig to establish the correct flow-rate compensation coding of the injectors costs in the region of 250k; not what your average diesel specialist will have in his workshop. Puling the injectors out under any force distorts the piezo element. I have seen cars where torquing injectors down to the wrong figure will cause a non-start.

    Secondly with regard to lubrication issues these engines suffer from. Firstly the sump capacity is quite small, yes there is a baffle that prevents all of the oil being drained, but the main issues are the long oil change interval, specifying a mediocre quality oil, and the *very* small oil passageways throughout then engine and up through the head which block with carbon, and lead to the cam seizing, the dreadful cam chain tensioner arrangement and oiling nozzle that blocks then the chain cuts its way out, and the propensity for the turbo to lunch itself, as well as putting extreme thermal strain on the oil. I feel that all of the issues are interlinked. However we have vehicles that the oil is being changed at 5k intervals with a good quality semi or fully synthetic that have covered 200k+ without issue. An injector or HP pump problem will result in a new engine being fitted. They are not worth pulling apart.

    As far as I know the DV6 doesn't use the newer style piezo injectors... they are bosch units btw...

    In terms of the oiling issue, what does that have to do with wether the injectors are referbishable or not...
    This issue has been elaborated on plenty on this and other forums. I would imagine everyone in the car/tuning/diesel/psa scene knowing about it...

    Mine has done 175000km so far without a glitch btw 20.000km per service interval on full synthetic cheap oil...

    didn't you close off your EGR valve? that'll go a long way in reaching the end of the oil change interval without building up sludge.

    Several measures were taken by PSA to remedy the problem:
    - using 5w-30 iso 5w-40 as the oil thickens from the soot, thinking the 5w-30 would flow a bit longer.
    - fitting shorter dispsticks on newer engines (you'll also get a shorter one if you order a replacement for your older engine), effectively increasing the sump capacity from 3.7 to 4.0 liters. I always slightly overfilled the older engines anyway (3.9-4.0 litres), since the turbo problem became apparent. Officially the oil capacity is still 3.75 litres I believe.
    - the air filter change interval got reduced from 60.000 to 40.000 km, as a filthy air filter increases the load on the turbo and increases the amount of EGR.

    I also did get the shorter dipstick, as I hated the factory plastic one and newer ones were metallic...
