[Umai Naa!!]

I'll report back, tomorrow.

Love to know the CORRECT part number for the new PD170 loom.....and injector.....

nice work Greg.

I wonder if it would be worth retrofitting silicone tube over the loom to protect the plastic insulation from the oil/heat (I mean, only if you were pulling all the plugs off the wires anyway

so do you want this thread stickied? Or maybe we can just put a link to it in the start of your fialure register thread....

In my opinion the loom *could* cause a short, but only where the wires all bunch together at the plug, as along the plastic holder they are held quite well. Certainly in my new loom, instead of 4 ground wires returning to the plug, the new loom only has one, so I reckon they have done that to reduce the chances of a short. Not a bad idea to put heatshrink over the one common ground wire though!

I feel the problem is oil entering the Pizeo portion of the injector, and there is apparently "better" oil sealing in the new unit injectors, which should hopefully fix the problem. Certainly once I get a bit more adventurous, or when one of my injectors goes, I think I will be investigating that quite thoroughly.

What interests me more is rumours of entirely different aftermarket injectors, and I'm putting all my efforts into trying to see if that is a reality, for I'd rather go with something else than hedge my bets on the same thing with a supposed better seal.
