Thread: Wiring loom harness AGAIN!!!

There doesn't appear to be any ready fix as yet, some people are experimenting with a couple of options such as sealants, but no results to speak of as yet.

Mind if I ask what business you are in and where?

Do a search - there are a few chaps who have cleaned out their own loom - and a few of us are trying to find a fix for it.

Bugman, considering the vehicle is now classified as 7 years old, I would not be worried about replacing the wiring loom. I would be inclined to periodically clean out the loom at the computer end and anywhere else that you have access to the loom.
A thought I have been having on my Disco TD5 with a similiar problem is to put pieces of cotton wool amongst the wires in the loom. This will stop some of the oil reaching the computer and it is then a case of periodically changing out the cotton wool. Checking the oil level in the engine couldn't hurt either at the same time.
My Disco TD5 is a 2000 model, and as it is also now 7 years old, I am at the stage I am not going to go and run off to the stealer for every little issue it may have (touch wood it has been problem free so far !!).
Bottom line, if you can keep the car on the road with a little improvisation and a tiny little bit of inconvenience (ie cleaning up the loom and the computer plug from time to time) then this is far better than being bent over and shafted by the stealers for a new loom which will not ulitmately fix the problem or last.
From looking at the injector harness wiring underneath the rocker cover, the plug has a very small hole in it. This will ALWAYS leak oil through unless LR have designed the same plug without the little hole. I siliconed mine up which somewhat fixed the problem (photos available).

Hi Bugman
Only replace the injector harness for starters,thats causing it,get them to clean the ECU plug and it should be mobile again.
I flushed my main harness with metho with great results,I think mines now back to 100%
If you do a search "flushing main harness" it should come up.If you cant find it yell out,I will have a look and post a link.

Brett.
cleaned mine with co contact cleaner(used for computer) about 12mths ago sofar no worries.

Gents,

Has anyone got photos that they can post (or have they already been posted?) of the problem at both ends? So I know what I am looking at.

Thanks,

Mark

Hello Bugman

I have had the same problem with D2 TD5 ... 3 looms later and the damn thing still leaks, however there is a quick solution.

My Landrover dealer cleaned out the ECU, (the oil in the ECU causes the main problems) then cut away the loom casing where the injector loom enters the ECU and put a sealant at the ECU end to stop dust etc entering the ECU.

Now any oil that enters the injector loom simply drips out onto the wheel arch. Not the best solution I know & I'm currently arguing with Landrover over who's going to pay for the next loom, but at least it saved me spending big bucks.

Give it a go, you've got nothing to lose.

Cheers
