Thread: Servicing TDV6 Injectors ..Can it be done?

Even if they are tecnically unserviceable units you could still have them ultrasonically cleaned.

Thanks Craig,

as of yesterday according to the workshop they have checked with various injecton specialists and they can't get them cleaned so if after testing they find them faulty they have said they will replace any that are not within spec.

If that is the case I won't be complaining if they are replaced, as I said the D3 is under used car warranty and the Dealership I brought it off so far are doing the right thing.

cheers,
Terry

Terry, before you spend big bucks replacing the injectors, run a tank with a 1:100 ratio of 2-stroke oil. If the injectors are dirty, this will clean them out. Thereafter run 2SO at a 1:200 ratio. Use a Jaso-FC spec oil but avoid fully-synthetic as this will clog your cat.

Thanks Naks,

right now as I said all the work is being done under warranty so if they need to be changed then it won't be costing me.

I was wondering has anyone else tried running 2-stroke to clean their injectors and what were the results?

There are some or at least one thread in this forum that I am aware of relating to the use of two stroke oil. From my recollection it only speaks about the lubricating benefits to make up for the lower sulphur due to the introduction of ULSD.

Do a search and you should soon find lots of info on two stroke use in diesel, not sure about content on the cleaning properties.

There is always injector cleaner produced by the likes of Wynns and more recently also on this forum there has been discussion relating to the use of 2 micron filters in the fuel system to give common rails injectors the best chance of not having to choke on larger gunk in the fuel.

Common rail injectors run at much higher pressures than older style injectors, if they have contaminated fuel run through them they don't last long as they rely on clean fuel for lubrication, water is the biggest problem for them that I have seen. These injectors can't be pulled apart and ultrasoniced like the older one either. Talk to a diesel injection shop and see if you can have water trap/filter set up fitted before the primary filter that won't inter-fear with your fuel flow rate.

Hi guys,

I had seen previously threads about 2-stroke being used but I had not noticed it being discussed about cleaning injectors and that s why I asked.

Given the cost of injectors I would not risk putting anything in the fuel that could contaminate them unless I could be 100% positive that there was no risk and only a upside to be had.

As for a water collector I intend to get one fitted when I get the D3 back as I do not want to risk this problem in the future.

cheers,
Terry

Hi,

Sorry to bump an old thread, but did the new injectors cure your cold start problems?

Thanks
