Thread: TD5 injector harness - a different idea

it amazes me the amount of time spent trying to avoid simply replacing the harness which fixes the problem for about $90 (every few years at worst case scenario )

Come on Ken, you know every one wants to reinvent the wheel
If it was such a simple fix, then surely the manufacturers would have done it before.

Well it amazes me, that some Land Rover owners always seem to have a poke at the Land Rover owners who want to try and fix something.
Regardless of the brand, I was brought up and therefore taught, that if there is something wrong with your car then have a go at fixing it yourself. All these people that just poopoo other people for trying to fix something, fascinate me. (too much money??)
I recently, seem to have fixed my injector loom, but haven't mentioned yet as I'm still testing/seeing how it goes. But apparently, instead of spending a weekend reading different forums from around the world, and then trying what I've read and learnt, I should just go out and buy a new one. Just coz it easier. Yeah, that's what I should do. Stuff trying to fix anything ourselves and then sharing it with others. Let's all throw everything out the minute its rooted and buy a new one. What a bull**** idea!

I get the angle you're coming from...

It's not fixing in this instance because it's not broken. It wears out... Like brake rotors, pads, air cleaners..

Problem is... You have gone and got some Materials, spent an amount of time, modified and changed things in the hope of a solution..
(That's the good / fun part).

The not so good part... You won't know if it worked or not...

I replaced the injector loom that was showing oil (second unit) when the head came off 7 years ago.

The replacement has not got a trace of oil in it...

What it does have, after 7 years, is a heat aged plug...

Like the cooling system hoses, coolant bottle, radiator etc. eventually the Materials age and need replacing.

Thankfully the harness is dirt cheap <$80 so when it comes to cost benefit, my time is more valuable and r&r is more cost effective.

I still hold one here somewhere sealed up...
As well as hoses, filters etc..

Reminds me I must top the stocks up - be in touch soon Mario...

Some people are lazy when it comes to thinking up a cure other,s might have different ulterior motives
But true what you say it pays to think outside the square . But realy some people think they have reinvented the wheel but realy its been done befor

Pricking the insulation on the wires with a pin or needle might work. What this should do is break the vacuum that causes the oil to travel up the inside of the wires to the ECU. It might also cause the oil to exit the pinhole before it reaches the ECU. Worth a try perhaps...

My own car lost power and started to run very roughly yesterday, so I'm hoping it's this injector harness issue, as I did find oil in the red plug. A few weeks ago I changed the ECU for a remapped one and was puzzled at discovering oil in the red connector. I could not find where it could have come from, and being a new Td5 owner, was not aware of the injector harness issue! Off to pick up a new harness today from our local Landy specialist.

In March 2013 and later I posted a couple of ideas to seal the injector loom.

I subsequently left my old injector harness to drain for 6 months or so , after buying a new harness.
I then cut each wire and put a crimp connector in line sealed at the end facing the multi plug but open at the end towards the injector. I also potted the multi plug with Araldite as above.

But you know what? I have never had to change the loom again. The new loom I bought seems to be well sealed at the multi plug and has gone now for 4.5 years. I checked it a couple of months ago. I have a look at the ECU and give it a spray every oil change, well almost every oil change and no oil.

Well, I call that a "result" Phillip A! I might just keep my old loom and do those mods as well. It isn't very old according to the garage that replaced the last one.

Anyway, I swapped out the injector loom today and the car started at least. It idles, but somewhat roughly and won't go over 2500RPM, so it's undriveable. Was I disappointed . So started going through a few obvious things, the first being the fuel pump. Guess what? Not a sound to be heard from it whatsoever! Looks like I have to replace it so will trawl through the forum to see how that is done. Whew, don't you hate it when stuff goes wrong and you start thinking the worst?
