Loss of Power and Car Shakes

[dbryant912]

Ye I have checked what I can, I think I'm going to remove all the pipes tomorrow and check them fully. Still just worried that the injector reading on no4 was high and also there was diesel in the power socket of injector no1.

You may not have read any of my chugging on start up threads but i did have problems for some time (not your problem but lots of injector removal & swap rounds), if you have any type of diesel leak especially from an injector it will effect all of the readings, Start with eliminating the leak at No 1 injector, Then if any problems persist its always good to remove & clean the common rail sensors & if problems still persist there's a sensor on the rear of the pump,swap around the problem injector/bores with the ones giving good readings & there individual codes, This will eliminate wiring problems per bore & pin point the problem injector if its faulty, But as suggested its always wise to really give your entire system a very close look over, even a very slight cut nick or split can cause problems & are usually never ever easy to spot, if it comes to injector swaps this can be done for ruling out purposes with the same injector seals as often there stuck to the injector when its removed, any further help feel free to pm.

Have you cleaned the exhaust, pre cat and cat out of oil?

[dbryant912]

I cleaned all of these out but stuggle to really give the cat a good clean. Also i was unsure if it could be a boost pipe because at around 2300rpm the boosts kicks in and it flys. Its just in the mornings it struggles to start and for about 20 seconds the car has no power at all. Seems like the engines flooded.

Are the pipes to the Vacumn thingy spilt or not seated correctly?

[dbryant912]

They all look fine but i did have trouble checking the long pipe going from the actuator to possibly the turbo. Ill have to check that later when its not raining. Am i right in thinking theres just the 3 vc pipes?

[dbryant912]

Today i have just checked all the vaccum pipes and all seems ok. I have also followed the guide on cleaning injectors and replacing the copper washers. Car now doesnt seem to want to start . Injector 4 which gave the faulty reading in the first seems to be spitting diesel out. When removing injector 4 the large nut about 1cm below the power plug at the top seemed to be very loose. Could this possibly mean my injector is faulty?

[the-wizard]

Ahhh!, you should be able to tighten that up, Another member had his back from refurb & that nut was loose, He just tightened it up, Be careful though & see if there's another part you can counter hold whilst doing it, One of mine came back where the elec connector was pointing at a slightly different angle but it was ok to connect so i left it, If in doubt remove it & hold it by the two flat sides lower down & tighten the nut just in case the injector clamp gets damaged tightening it in situ.

[dbryant912]

I have managed to sort that out now but now there is small bubbles coming from injector 3.

I did have this coming from injector 4 but i did tighten the nut just half an extra turn and now that injector seems ok.

I have tightened the the nut on injector 3 but i am really worried about over tightening it as this has already been tourqed to just above 25. There is a small pool of diesel just around each injector and i was unsure whether or not it is normal for a tiny bit of air to leak and maybe this is causing the bubbles or whether there should be nothing leaking at all from the injector.

Can anyone recommend a good way to remove this diesel without having to take the injectors out again or is there something im not doing to get the copper washer to seal?

Thanks for all your help so far everyone.

Here are also my new readings after replacing the seals.

[the-wizard]

If you have to remove the injectors again try a smear of grease each side of the copper washer,I always used to do this when i had my own trucks simply to hold the seal in place & when the grease burnt it helped seal them, I had my cdti injectors out several times & used the same seals 'no probs, just checked torque & its 25nm so they should be ok at that or maybe 30 at most.
