Wrong Way... is to use that box of tricks, its a good try but its really not going to help much, it will just fill with oil, but in no way solve the issue.

His sugestion is, if you wish to use the box of tricks, is fill it with Silicon...

Solution from a LR expert with factory / design heritage in LR ... get a new harness, fill the barstard with silicon, and install.

155$ solution ... the rest will just prolong the problem!

$155 is like two fuel tanks of diesel and the problem is solved!

Well again - you may be spot on -

However silicon will break down, in the oil and heat - and I wouldn't put it in any connections inside the rocker - because when it does break down it will go somewhere, wouldn't like to guess where and what it could do.

The reason I wouldn't fill the box with silicone is that I want an 'open' space to allow the oil to drop out.

The box will not fill with oil, it has a drain fitting on it, and if the oil is seperating out into the box - it's working, and any oil that does drips down the drain hole - connected to a looped hose.

Again you may be 100% correct - but after all the posts on the problems, people who have siliconed and it has failed - I just thought I would try and help with an alternative approach.

once youve had the oil in the harness problem you should be replacing the harness you so will be no worse off trying the mods But I would order the harness first or find out where one is on shelf... if it turns pear shaped so long as I have an inch of wire before any plug or socket and the colour coding is intact I can fix it. Iif I have to I'll template it off of big red, that'll take a day but it will be fixed.

and ill put the BBQ on, ive checked my plug at the head and there is nothing there yet. How about your Extreme Dave have you had this problem yet.

Nope big red is squeeky, but big red has only ever run synthetics and I check the plug once a month when I do my suspension tyre and cleanout of the back.

Bet it can.

for an offer, once im on the ground while I experiment with my fix which is similar to ladas's but different anyone who already has the oil contamination problem is welcom to drop by while we experiment...

The only guarentee you get (as I'm not currently decked out for dealing with the ECU or the head harness) is that your vehicle will start and move out of my driveway. As Im sure its my turn next I'm trying to source the harness and I'll keep that onshelf for callout replacements to people who have the fix done (if you live within about 100k of me).

Do you plan to cut the 7 wires, and insert the box under the seat ? ...

There is silicon that will not degrade .. once i do mine (very soon) I shall tell all!

Nope, the box will be in the engine bay, at a convenient, and high up position.

FFS a new harness$130, I'm prepared to experiment.

Considering the noise, heat and moisture in the engine bay in rain/water etc..
I estimate (in fact bet) that this box causes more issues than it fixes.

Right up to complete arc of 85v and an ECU failure.

Remove Harness pins from plug... strip 10mm tin them (to seal them), heat shrink over them, no leakage then.

BTW, Crump your right...

$150.00 for 80,000kms... Why bother trying to stop it...
I'd rather not introduce a failure point.

yeh, but i still havnt done 50000kms, and introducing a failure point, dont I already have one?

1. Has anyone got a 03 - 04 TD5 and had this problem?

2. Has anyone replaced the harness with an all new version and had this problem come back?

**crump** · 7th February 2007, 11:26 AM

mines an 03.

**stevo** · 7th February 2007, 11:35 AM

you are right about silicone breaking down in oil,I have seen one motor stuffed because when he had it overhauled they used ORDINARY silicone that you would use for sealing glass,the stuff I used handles oil and temp.

I also had to replace the plug under the head so about 100 mm I cut the wires soldered the new plug in and used the heatshrink with the glue in it to seal up the joins.

here is a pic of the dodgy repair I did had to do this to get home from the mother inlaw as I used her garage to do the head gasket the old plug had split and would not stay in a bitch of a job to do but lasted three weeks till I got the parts needed wasn't willing to pay for a whole new harnesscar repairs 015.jpg

and nothing tried nothing gained that is how we learn and if something we tried doesn't work then we can say no do not try that it did not work for me
