Went out for lunch today from work. Truck started cutting out and backfiring badly. To make a long story short I've burnt up the third plug wire in about 6 months on #5 cylinder. My first thought was the plug wire but when I pulled it off the first time I didn't see the problem. Wound up putting a new set of plugs in. When I pulled #5 plug it was sooted so looked at plug wire closer and found the crack. I've tried 2 sets of expensive heat/header boots. Thinking about making up some brackets to hold them away from the headers but that would be a PITA. Anybody got a solution?

 

Here's what snakeoiler did. I remembered thinking how clean and effective it looked when I saw your post:

That looks like the ticket. Dynatech needs to put those in their kit! Thanks so much

 

Man. Good thing that primary has that funky *** bend!!

 

No kidding! With all the room in that engine compartment and they have to make that #3 primary 180 like that. Then to top it all off, provide no help for your plug wires. Sheesh.

Those little sheet metal brackets are still hanging in there. I have not had any problems with the wires.

 

thats is clean looking i just used zip ty's to the ignition bracket

 

wonder why they do that one primary like that? are they equal length?

 

i was told they do it for the steering shaft but that other guys make it work out, i guess it was to close to teh block or pan

 

I'll be okay with zip ty's temporary but I think the factory wires are shorter than yours appear. I've also still got the factory metal plug boot cover on them which doesn't help. Brings the wire out closer to the pipe. Don't know if I can get them tied up there. Worth a try.

 

Are you using the factory wires with the metal heat shield. Are they the ones for truck. Think I read that vette or LS1 wires are a bit longer.
