Thread: Oil in wiring loom

Buy a new one, solder the copper strands at each injector plug, fill with hi temp silicone, close the plugs once sealed and it will never leak again. Just keep cleaning the RED ECU plug with contact cleaner until no more sign of oil.

JOB DONE

Cheers

Can anyone estimate a dollar value of having a literate mechanic perform the task?

They cost about $80 and it takes about 30 minutes to change. I had mine out twice on a recent trip to Brisbane and back from Darwin.

Just do it yourself. Take off the acoustic cover (3 Bolts), 10 or so bolts out of the tappet cover, It unplugs at the front, whip it out and throw in the new one.

I recommend changing the tappet cover seal at the same time.

Follow these instructions. Mine didn't have oil past the first connector so it didnt make it to the ECU like the this one : www.discovery2.co.uk / Workshop /Injector Harness

Happy Days.

If you are not keen to solder/silicone the loom yourself, you can buy a modified one from various LR dealers around the country. One to try is MR auto, Redcliffe. Bear in mind, there will be residual oil in the engine loom for a while, check the red ECU plug every 5000 kms, until the oil is no longer seen, all good Bob

If you are asking about the Engine Harness, I got one from the UK for 155 pounds + 70 pounds freight. Cured many engine management problems. Sometimes the loom gets to the point it is best replaced, but not without the replacing the Injector Harness as well. Not a difficult job, I would say about 2 hours for a decent mechanic to replace the Engine Harness.

I thought it was only the injector harness required. As the previous posted stated the oil will continue to run out of the engine harness for a while and you may need to check the red plug a few times. It's the injector harness that causes the problem.

Happy Days.

Thanks all. As a result of your posts I am now confident enough to have a crack at this myself!
