TD5 Defender - Oil in injector harness

Anyone else had the well known issue of Oil travelling down the injector harness and pooling in the plug to the ECU ? And what is the best fix ?

Swap the loom out, parts £40 and about 1/2 hour to do

As above - I researched it in case I ever had to do it, the parts were £40-50, and it wasn't super hard job, although I might allow a bit more then 30 mins to complete for the first time! Thankfully in 9 years of ownership I never had to do it.

It's been written up various times in the mags as a step by step guide, and from a quick Google, there's loads of forums/blogs and YouTube videos on how to do the swap.

I vaguely remember some people initially using contact cleaner or something to try and clean the pins out as a temporary fix, but given the cost of parts and relative ease of replacing them, if this is causing a problem on your vehicle, as per Lee, I'd just swap the harness out.

if there is no oil under it, there is no oil in it.

Take off valvecover, remove loom to injectors, clean valvecover gasket and aply liquid gasket. Install cover.
In following weeks clean red plug in computer with brake cleaner.


Repeat in 5 years or so

I've never worked out why oil affects the connectors? What actually happens?

It's a very common TD5 issue.
Here done on a Disco 2: www.discovery2.co.uk / Workshop /Injector Harness

AIUI oil is generally not a conductor of electricity but I would expect the contamination in used engine oil might change that & cause the problems?

It doesn't really affect the connectors, but if left for a long period of time, the oil will enter the computer and there it will destroy components.


Every 10.000 km's your car needs service; a simple check of the big red connector is part of that checkup.
