replaced plugs, brittle wire loom falling apart
When I moved the coil pack wire, the wire loom were very brittle and fell apart. I seem to have read other people observing the same.
What do you guys do? Buy new high temperature split wire looms to replace what is there or leave it as is. The wires that feeds the coil packs are definitely more exposed now as chunks of the wire loom fall off.
Thanks, I'll get some to replace it
Looking at what is there. Looks like I need at most is
1 foot of 1/4"
2 feet of 3/8"
1 foot of 1/2"
Maybe this will help avoid so much disintegration
I realized a method after my plug replacement that may have saved my wire loom from so much disintegration. The distintegration comes from movement of the wires. You can disconnect the wiring harness from each coil so when you pull the coil off the plugs, the wiring harness doesn't have to move much. The connector is right on the side of the coil. This may limit the disintegration of the brittle loom.
The wire looms are still brittle but I guess it will perform its intended job of keeping the wires's insulation out of direct contact with the head.
I also see a mostly disintegrated wire loom off the connector just above the power steering pump on my car. This is the exact same < 1/4 ID tubing in the coil pack wiring harness. But the wire's insulation appears to be fine.
I also found 3/8 ID split loom at your a home improvement store (Lowes here) which said "high termperature resistent" without any more info. But they didn't have anything smaller than 3/8 ID. Someone also suggested checking with a speed shop. I didn't have a chance as I had to put the car back together for next day's ETM replacement appointment :-)
200+ miles into my newly installed and likely low temp loom, they are still flexible in original condition (a quick check by only removing part of the cover near the timing belt - no need to remove turbo pipe) So I'm somewhat confident they aren't going to melt but maybe will get brittle. I'll check in a couple of thousand miles and report back.
Resurecting an old thread
I'm about to tackle fixing the disintegrating loom on my engine harness, and have a couple of questions.
1) Does anyone know of a very high quality harness tape that could be used IPO the split loom. When I used to work in the auto industry, we used some nice fabric type high abrasion resistance stuff, but I can't seem to find a retail source.
2) Second option, does anyone know the recommended sizes/quantities of split loom required? Or perhaps someone makes a repair kit?
Thanks for any input
