So, turns out my joy was short lived, for a while this morning anyway.

Mrs needed to go into work until lunch and I wanted to pick up a new hose pipe so I said I'd drop her off on route.

First set of traffic lights, about half a mile down the road and I can smell diesel, so can the Mrs. Great!

So I dropped her off, luckily not to far, and headed back home.

Popped the bonnet and it stinks of neat diesel. Can't see anything though as all the covers were on.

Front cover off and I can see diesel dribbled down the front of the engine. At this point I'm thinking it's a union not sealed properly.

Rest of the covers off and it's obvious that the leak is coming from somewhere around the leak off at the top of the injector.

The trough around the injectors is puddled in diesel, esso super diesel at £1.30 a litre I might add!

So I eventually cleaned it all up and convinced my self that the t piece on top of the injector hadn't sealed properly. Take it off, clean it, clip it back in and fired the car up.

At this point I can physically see the braided leak off hose between 1 and 2 getting wet. So I'm thinking the rubber must have gone brittle when I disturbed it. Got some leak off pipe out of the shed and replaced it.

Now I can see the braided hose that runs from injector one back to the pump getting wet!

Replaced that. Try again!

Now I've got diesel forming on top of the injector!!

Pulled the t piece off and examined the o ring and noticed a tiny nick in it. So I went up to the diesel place and picked up a new o ring which cost me £0.00p, fitted it, problem solved!

Note to self - always replace that o ring if you remove it!

Still not washed the car.....

Brass connectors look fancy but I'm hoping that I've seen the back of it!

I actually ordered a replacement t piece in anticipation that I was going to break the original.

It arrived this afternoon so at least I've now got a spare.

I've fitted those brass injector bleeds as i got fed up with the plastic rubbish breaking / leaking, well worth the investment.... I've got them on my Merc too  Yesterday I couldn't spell Engineer... Today I are one!

Miggit, I totally agree, they all go brittle along with the hose degrading so it's only a matter of time. 2007 TDV8 VSE

Great post Paul, really helpful.

When I connect up IID it only shows a reading for the injectors at just above idle - when running on throttle they all just show max value ?663mm3

When on or just above idle some show 0 some +5 and some still show max value

Just wondered if this was similar behaviour on yours?

Hi Paul,

Sorry for the late reply, I missed your post somehow...

What symptoms have you got?

The maximum leak off value I saw on mine was 7mm3 and that was with a dead injector. The first number, I believe, relates to the leak off so obviously you want that number to be as low as possible. My new injector reads -1mm3 and all the rest between--1mm3 - 2mm3.

I found if I unplugged an injector with the engine running I got a 7mm3 figure for each one so in my case that was the maximum leak off value.

The figures do change as you rev the engine and I suppose if you had a miss fire at a certain rpm you would be able to identify it there. Mine was mainly at tick over so they were the only figures I was interested in.

Using Faultmate mine reads all zeros when I rev the engine.
Mine is all good now I have fitted a brand new injector wiring loom.

That means all the injectors are ok then.

Glad you got it sorted.

Thanks for the feedback Paul.

The Rangie has always had a small vibration between 50-60 but only when on part throttle. This has started to get worse over the last 10k and now is quite bad, also starting to notice what feels like a misfire at low revs. Gearbox has been overhauled about 20k ago so don't think it is that.

So thinking injectors. Need to get under the hood and start disconnecting individual ones and playing with the loom to see what happens. It was just the IID behaviour seemed odd, it basically only records just at idle or above, anything other than that and it shows this value of 663 across everything.

Also don't get many of the fault codes showing the explanation on other stuff, just the hex value of the fault code "00xx0000 fault unknown" so maybe something wrong withe the IID I need to look at.

If it is injectors at fault you should get other faults logged as the EMS tries to balance out the cylinders.
Vibration between those speeds under light throttle load can be torque converter and without wanting to worry you too much some TD6 transmission refurbs only last 10K if the valve body isn’t refurbished which is the route cause of TC failure and following transmission destruction.
What other faults are you getting logged in EMS - Edit sorry reading your post fully your fault codes are in question ?

30-52 MPH is the more common TCC vibration.. 50-60 is more likely to be a dirty, blocked injector.... it doesn't matter which diagnostic unit you have plugged in, it wont detect blocked nozzles.... A blead off test is the only way! Yesterday I couldn't spell Engineer... Today I are one!

Thinking about it, I just took all my injectors out and sent them to a Bosch agent to have them cleaned and tested, 2 failed and needed new guts, after the engine was the smoothest I'd ever known it.... If you car has done 80k+ then a complete clean of the injectors will give it another 80k's worth of life... And I had mine done at 110k, just after it all failed 200 miles away from home with a 3 ton trailer in tow

FYI 'cleaning' the injectors is a standard service activity on a diesel engine... only LR haven't included that in the schedule... they'd rather just sell you new injectors @£350+  Yesterday I couldn't spell Engineer... Today I are one!

I agree, and tbh how much difference its made to mine just replacing one injector, I'm thinking about removing the other 5 and getting them tested / cleaned.

The injectors will probably still be be working but you can almost guarantee they will be partially blocked causing an incorrect spray pattern which will result in poor running at certain rpm etc.

I'll do a leak off on mine when I get chance just for curiosity more than anything.

I strongly believe it's the egr valve that causes them to block which is why I need to get rid of mine asap.
