The biggest aid to the problem is the fact that the male section is in the head and the female part is the lower "catch cup" and the spare unused pin holes in the connector direct the flow into the harness.Its not possible but simply reversing this connector would allow the oil to leak out over the connector rather than pooling in and draining internally.
Keep up your posts Im sure with the combined brains trust here we will get a simple solution.Once mine is clean Im willing to risk cutting the harness and fitting an extra connector.My Mrs is an ex-electronics assembler so should be able to do it.

Read this after replying to your PM

The reason I thought I would go the 'box' way was for a couple of reasons

1. You can mount the connectors on the box, keeps it neat
2. The box would offer some method on fixing to something so it didn't just flap around
3. Instead of the excess oil dripping anywhere - it could be directed to a tube fitted to the box and run to a suitable location where when you looked you didn't need to ask where is that bloody oil coming from.

If your misses has that experiance - I am a bit ham fisted, might be the better wat to go. I'll get something down on paper and post it here.

Attached are my ideas - for what they are worth

Appreciate views/comments (keep it clean please) :)

Hi All
This might stop the oil getting to the ecu but it will still get to the plug on the out side of the head and thats where I thought some of our problems comes from as the oil inhibits the the signal to the injectors.

According to all the chaps I have spoken to about this - it does not cause a problem until it reaches the ecu.

The oil shouldn't inhibit signal - in fact (in theory) it should make the signal clearer / or should I say reduce the resitance

Only Land Rover could make a computer that leaks oil. :D

Hi Ladas
Great stuff.
Looking at it it should help.1 thing that I thought as soon as I looked at it was,a socket on one end that matches the TD5 wiring and a tail on the other so it would become "plug and play",no need to butcher the exsisting wiring.The oil shouldnt cross the LEDs anyway.If it does work we could be onto a winner.Off to read your PM that just popped up.

Totally agree, but what is the cost of the plug/socket config - are they easy to get -

with the RS232 (D9) - I just looked at how many pins/cheap/available

I would think they were "off the shelf" BUT WHOS????
I will see if my boy still has his DSE cattledog.

Hi All
I have done a little more research into the harness issues and found the following.
1.Thank you for your inquiry about Permatex products.
You will not have a concern when using Synthetic motor oils in place of standard mineral based oils in regards to Permatex Gasket Silicones. Test conducted by Permatex where Silicone samples have been emersed in oil which is far beyond the conditions found in a motor have shown some minor reduction in the products rigidity, flexibility and elongation. However the products properties were still well above the requirements needed in even the harshest service environment. This cannot be said about all silicones on the market.
For your particular job I would use Ultra Black as it has the greatest flexibility and oil resistance.
Ultra Grey is best for High torque applications (transmissions)
Ultra Copper is for High Temp. (exhaust manifolds)
Ultra Blue which was the original is now regarded as a general purpose gasket silicone, Pretty good for any job as long as it is inside the temperature range.
I have attached some TDS files on each product for your information.
If you would like more information or product catalogues please feel free to contact me with your postal address.
