looks like they have a TD5 DPL modified injector harness

dosent get much of a mention
anyone know anything about this?

I rang them a few weeks ago and was quoted over 200$ for the harness with no guarantee that it will keep oil out for good.
So I decided against it.

If you buy a hi temp potting mix , you can treat a (NEW) OEM harness to stop the oil getting in. , waste of time trying to treat a old harness
something like this.

Encapsulating and Potting Epoxy Compound > RoHS Compliant

goingbush,

Have you tried the epoxi bond on the harness?

If so would be interested in the results and where you applied it. At the injector fitting and or the loom connections.

As would I .......

The new harness has some kind of epoxy mix filling the space where oil used to travel to the engine harness to the ECU. It's my understanding that there is residual oil in the engine harness to the ECU, which will work its way thru over time. I had the modified harness fitted 3 years ago, and check the ECU plug every service, after 3 services [ 15,000kms ] , there was no oil visible. Bob

Yes, I had some of the goop left from a job at work,
put it around the top of each injector plug (on a new loom) where the wires are visible, and injected it into the hole in the canon connector where the loom wires go in,

about 20,000 klm ago, so far there is no evidence of any seep into the external connector,

I didn't actually seal the external connector but will do if the new loom starts to leak. To seal the external connector I would carefully strip back a short length of insulation from each wire under the canon plug and re insulate the conductors with encapsulate, one at a time, then enclose them in a suitable housing & flood it with encapsulate, That way even if the loom leaks its impossible for the oil to get sucked in between the conductors and insulator, thereby stopping the capillary action.

Hi all,

I have recently purchase a 1999 D2 TD5 with 315000km's on it. It is running great but I am concerned about this problem. My question is as I do not have any history if the loom has been replaced/modded or not how do I check. After this many Km's could I assume it has been done if showing no issues or can it happen any time. Should I replace it anyway or wait to see if it plays up.

I noticed the other day that Jaycar sell potting compound kits. It's only a small pack but was about $10.00 from memory.
