Author Topic:   Spark plug wires falling off
posted August 28, 2004 07:09 AM
I put the little plastic tie wraps around my spark plug boots, snug em down to hold the boot tight.
My #5 & #7 wires run right below the throttle rod, is there a way the rod could be catching them and pulling them off?

Coudn't you just smear some light adhesive (silicon like?) on the ceramic portion of the plug? Then it, once it dried, it would hold the boot to the plug.

Wouldn't put too much on it though so it wouldn't tear the inner lining of the boot.

Just a thought....

We had the problem on our modified and finally figured out that it was trapped air getting hot and popping them off.

1: Get a small coffie stirer straw and put it into the wire end, push in the wire and pull the straw out. This will let the air out.

2: Get the Motor up to temp and push all of the pulg wires on and twist them around. This will allow any pressure to be released and help keep them on.

We have done both of these and solved the problem.
We did have one set of plugs that still did it and we could not stop it. While in the shop I watched it pop off and we found out the plug had a small amount of blow by on the shaft between the element and the porciline.

Hey ego, could you just drill a small 1/8" hole in the boot to accomplish the same thing? (just a thought)

You could but that would be a location for moisture to get into the wire and cause a misfire. Our Super LM already has a love afair with moisture in the dist cap. We run 180 degree headers on our mod and it is not that hard to use a small straw. On our Super we get it hot and push them on and twist them around.

I like the tie wrap idea, I'd never thought of it, once you get the plug wires on tie wrap them to the plug itself
