Thread: td5 oil in harness

I read on another unrelated mercedes forum that you can prevent the engine oil wicking through the wires by stripping the outer sheath near each injector and soldering the wire strands solid then epoxy over the soldered area. Obvously on a clean new harness. What do you reckon?

That sounds like a great solution for the cable that exits the bottom of the canon plug , where it comes out of the rocker cover, its easy to get to & easy to work on, Even if the loom leaks the oil can't get past the soldered part & won't wick down the loom into the ECU.
