Thread: Oil in injector harness loom - advice wanted

Hi Martin
Best to replace the injector harness,they are cheap enough.
If its not missbehaving yet you may not have alot of oil in the main loom so you may get away without cleaning it.
I would remove the seal on the red plug at the ECU asap and only replace it when the oil stops flowing or before water crossings/4wding.Clean it and leave it on the console or somewhere similar as a reminder to replace it later.
Make sure the ECU is replaced with the red plug to the bottom to ensure better drainage.

As I understand it Martin it's nothing to do with the O rings, the oil on mine had got in at the injector plugs and wicked inside the wire all the way to the connector at the front of the head. When you take off the top cover you will see what I mean. the injector sockets have a little drain hole, but it's on the top side so they fill with oil and eventually this gets past the seal and that's it!

I'd just replace it, clean the old one at your leisure, and keep it as a spare.

when I repleced mine i did it quickly, I didn't have as much time as I would have liked to have a proper look at how it is set up.

I DO think that changing the o-rings would work buecause of the way that the plug is orientated, the female part is on the lower side so the oil drains in to it. if it had been the other way around I dont think that the oil would drain to the ECU.

Jsut my thoughts, I had already got a new harness by this time and have kept the old one 'because'

I wonder how many have been kept for 'because'?

It's all about stopping the capillary action!

Mine took almost 9 years for the oil to reach the ECU. Replace the harness, stop the flow of oil and do it again in 8-9 years.

You can buy the harness cheaper from UK ebay and then follow instructions from this link.

I guess that I should have a look and see what sort of a mess I have before I go ahead and buy a new injector harness although I fully expect that a new harness is on the cards.

If there's any doubt I will replace it. I like things to be done properly and as Andrew says, they're not that expensive. Has anyone used one of the UK suppliers to buy one? They do seem cheap at under $AU100.

Thanks to those who've helped so far.

Martin, mine was $109 from ULR in Melbourne.

Thanks Fraser, I'm in Canberra so I'll get a price from our one and only LR Dealer before I order off ebay. If it's only $20 difference it isn't worth the wait to get one from ebay!!! even though the car is not needed and can sit for as long as it takes.

Hi Martin,

I am in Canberra too (Monash), & I think you will need a bank loan to buy it from our one & only stealer. Try british4wd.com 03 62347444 from Tassie - they have the injector harness for about $170 or All4x4pares.com.au 02 4957 1117 from Kotara NSW . I think both are good to deal with & you will have the parts by end of this week or early next week. Look on the net there are plenty to choose from in Australia. If you dont want to do it yourself try Canberra motorworks in Mitchell - he knows his stuff about landy's but might be a few $$$$.

I also have the injector harness problem but I haven't done anything about it yet -- except to take out the seals on the red plug & clean it out using WD40 & air compressor every 4 to 8 weeks.

Hope this helps
Steve
