I think 800 is too cheap to refurbish the injectors. I also sent my injectors to a company (in germany) which destroys them for 1000€ :mad:. The engine was running not so bad like yours but when warm unsteady. They have fittet not original too big nozzles and misaligned the mechanic internally...

Too bad to hear an injector swap didn't help, you are the third person i know changing the injectors without luck. I've made some measurements on my engine just because of out of curiosity. First, i've done a vibration measurement with the app i told before. When engine is at operating...

Sure. Next thing is to identify the cylinder which is knocking - I'm really interessted in even though the car is running.... Question is if it's possible to pin out injector by injector while engine is running, if this doens't damage the ECU or injector... Before that i will try other...

I think this procedure can be valid if you know which cylinder is currently knocking. Then you can check if knocking moves with the injector or not.

Do you have solved the issue? I had also air in the fuel system, didn't get it out. Coincidence helped me: I was working on the pump and for one week everything was ok....then the issue comes back. I decide to temporarily tighten the fuel lines with cable ties and the issue was gone I have to...

Most people are saying this sound is OK but the uncertainty remains. Another theory is that it has something to do with the pilot injection. I know the TD5 is doing this and the last digit of the injector code is for idle speed correction. Maybe this value "moves" while operating temperature...

Head swap was done by a guy who is specialized on Defender and other Land Rover. Additionally the following parts were exchanged: Hydraulic lifters, glow plugs, chain tensioner, Diesel pump, fuel pressure regulator, air flow meter, small harness and the injectors. The injectors were a pain...

Hi, you are not alone! I got the TD5 with Diesel in oil, so i changed the head immediately (AMC). Because of this, i didn't know the sound of the TD5 before. Injectors are reconditioned. I'm also little bit nervous about the knocking sound. I've made two videos, one warm and one cold. It's...

Hi.....I've made another video when my engine is cold and was started for first time on the day. The difference is audible. It would be really nice if the engine would always sound like it does in cold condition. My fear is that in the long run the engine will be damaged....

Thanks, next time i will try the other oil - maybe ;) Today i've had some fun on the unpaved road and observed that this knocking sound is going away when I'm in idle rev going downhill, so it has something to do with the injection/ignition of the diesel. I cannot find any issue so far, it's...

I'm certain about the injector adjustment, because the other injectors had the same sound and these were mounted by another mechanical. The interesting part is, that i only hear this sound when the engine warm, maybe this because of the oil or because of the rev speed is higher when it's cold...

Yes sure - it's Eni i-Sint SAE 5W-30 filled in. Do you know what is causing this sound...is it an injector, is it the ignition itself...?

Hi, i've got a set of reconditioned injectors and the idle is now steady and the engine is running smoother. The first recondition was going really wrong! The last thing i have is now a knocking sound when the engine is warm. Please have a look here https://instaud.io/3Y3a I'm not sure how to...

I've fixed today the high/low switch which makes no difference with my issue but now the Defender is much better on gas. Another set of injectors will be really luxurios :-) Unfortunately i didn't have one and the prices are really high...

I've cleaned the connections of the clutch switch and fuel temperature. I've also disconnected these two connection when i have the issue without success. I've found out that my low/high switch was not working, the ECU thinks i'm always driving in low, not sure if this can cause the issue...

Besides of the fluctuate rev, the engine is running like charm and i didn't have the issue everytime....i assume if an injector is the root cause the issue should be stable?

Hi Everyone, i've an TD5 MY2002 (15P) with ~180.000km. Sometimes i've an unsteady rev. I was notice this behavior first in idle. I've a "test track" where i can reproduce it by 100%. The track has 8km and is upwards a small hill only some meters. When i arrive the idle is unsteady. When i'm...

The hydraulic lash adjusters have been replaced and the issue was gone :-) Thanks for the discussion...Best Mario

On 3 cylinders is compression down, don't know the numbers exactly....

I didn't know, the assumption is that this knocking sound is because of not closing valve, we have to check. Question is, if there are other options which are creating this knocking sound from intake....
