I am changing the leaking rocker cover gasket and front and rear cam shaft bore seals. I thought I'd change the injector loom as well, as a preventtative measure. I removed the engine loom plug from the head and bugger me sideways it had oil on it!! What a suprise. I have a couple of questions.
1/ How can I remove the oil from the engine loom?
2/ I have seen a couple of video clips on replacing the loom. One used a rubber mallet to fit the injector loom into its hole, [bigsad] the other one said use lubrication, use engine oil? or a water based lube like KY?

Thanks in advance

Julian, FWIW I had no need to use force to refit injector look plug, pushed in with only moderate resistance. To clean oil out of engine loom I pulled loom out, stripped the tape, hung from rafter and used contact cleaner, brake cleaner and compressed air. Took multiple applications over several days before I got all the oil out. To be fair, I had a lot of oil in the loom, so this level of effort may not be necessary.
Cheers, Charles

The problem is not so much oil getting into the injector loom as there are no seals on the injector plugs and oil will creep up the wires.
The problem is that the seal on the plug lets oil through into the main loom and it migrates up to the ECU and then into it and causes shorts betwen pins.
I pulled my plug and laboriously split each wire and used butt connectors to isolate the oil and filled the plug with silastic.
However the loom that I bought about 5 years ago has never seemed to leak through the plug and I have my modified one hanging up in my garage never used.
I think the later ones have good sealing on the plug, so buy a later one and hopefully have no problems.

As for the oil in the loom, this might be a while as the car is my daily drive. Time to check the RED plug.

Go back 10 years in the archives to search on this. The oil is in the wire core itself so washing the outside of the wires does nothing.

Change the injector loom every so often and keep the red plug clean. Also take the sealing rubber out of the red plug so that the oil can leak out and not accumulate in the plug connectors.

I have seen everything now with the ****** hitting in the plug with a rubber mallet. (although I must admit to tapping injectors in with a light nylon mallet)

The problem BTW is not the outside of the plug leaking, that would only drain down to your alternator.(ha ha)'

That is actually the sole purpose of the front camshaft plug so no usurping here thankyou.

The problem is that the old plugs were not sealed well inside where the male leads went into the female plugs.

Where can you buy the female pins that go into the red ecu play?
