Plug wire order/from the holders to the cap

[Richard G.]

I noticed in the assembly manual there is a specific order that the plug wires are attached to the holders as they move up the side of the block and into the cap.
Is this order something that is judged?
Thanks

Since you have to remove your center shielding for judging I would think any gross mis-routing would be seen but I'd have to check the JG to see if its a point hit - I would think so.

But why not just do it right....between the AIM and the fact that the rubber wire looms are marked with plug wire numbers its not difficult.

Positioning is specified in AIM and visible on big blocks. I don't recall it as an item to check on the judging sheets.

Hello
There is a line on the judging sheets "Spark Plugs and Wires"
The routing through the holders is important to help eliminate "crossfire".
Routing also makes for a clean untangled professional appearance.
I would not deduct any points for incorrect installation.

just my .02

Thanks for the great information.
I didn't know the rubber wire looms should be marked with plug wire numbers.
Mine were not.
Even though mine aren't correctly routed they looked good.



Anyone have pictures of the separators with the numbers?
Mine are really old but were replacements. I will have to look closer at the ones that were on the car to see if they have the numbers on them.

Here are Paragon examples - the numbering is a bit confusing but its designed so that any loom can be used on either side of the engine in either the upper or lower positions.. If you examine the AIM spark plug wire routing you can match the loom numbering to put them in the right position...

Under the NCRS judging the CDCIF is supposed to be applied if the wires are routed wrong it is an assembly error and is subject to a 20% deduct in the wires and spark plugs area. Just because a particular mention on the judging sheet does not read an issue does not mean it is not judged in the area it is in. The judging guide is just that a guide it does not hold your hand nor replace logic.

I want to thanks everyone for their comments.
Just when you think you know something about these cars, something this simple comes up and I find I hadn't a clue.
I suspected my wires were routed incorrectly as soon as I saw the detailed diagram in the AM.
I had no idea about the numbering system built into the rubber separators.
Likely be good advice to have the assembly manual opened up to the area you are working one anytime you replace/redo anything.
Just like exactly what is required when you work on aircraft.
I plan on reordering my wires and will purchase replacement separators next time I order.
Thanks

Good news:
I found the wire identifiers embossed on the back side of my existing separators.
If my eyes were better possibly I would have seen them earlier?
It was quite difficult to slide the separators out of the holders.
Even though they had only been on a running motor for 300 miles.
I used a small amount of silicon lubrication on the sides of the rubber inserts when putting them back together.
Should be easier to get them apart. I had to pull so hard I was afraid I would damage the wires.
Squeezing the holders together slightly, at the open end, helped retain the lubricated rubber inserts in the holders.
Should be good.
Thanks

Sounds like you got things sorted out now Rick...good deal..
