When Mike did my Td5 Re-Map, the usual oil was found in the Injector Harness. I intend to replace the Harness asap. Is there any way to stop the oil getting back into the new harness again, or is it just unstoppable.

wouldnt help it would only stop a leak from rocker cover, not into connectorWhat if the o-rings on the injector loom plug are replaced at regular intervals, hopefully making the change before the seal is lost? I would be quite happy to fit them rather than risk getting oil in the ECU.
What stops the oil getting into the loom if it's not those o-rings?
Disconnect the battery before unplugging the ECU of course!
As ^^^^, fit a genuine LR injector harness and clean the red ECU connector at the same time with electrical contact cleaner. Disconnect the battery before unplugging the ECU of course! The oil that is already in the loom leading to the ECU will keep seeping down to the ECU so you'll need to keep cleaning the ECU connector every few weeks for a month or two. After that it should stop.
The seepage is due to the o-rings at the end of the injection loom aging. Some people have managed to cure the seepage by renewing just these o-rings but the generally accepted cure it to swap out the injector loom. Its also generally accepted that the non genuine looms only last a year or so before leaking, hence the recommendation to only use a genuine one.

How do you get the ECU out? The earth lead on mine has to be disconnected otherwise it's in the way.
I thought it was LR's cunning way of ensuring the battery was disconnected.......
The 'O' rings perish with age and thermal cycles. Read this it helps to explain it and how to sort it : www.discovery2.co.uk / TD5 Engine - Injector Seal Replacement
So is there a part number for the O rings Dave?
