Default #5 spark plug wire problem! HEADERS!

Hey I have a little bit of a problem with the old Z latley. I have not driven it much but I was out in the garage today and I decided to pop the hood and check things out. I checked all my wires and they are all fine but #5. The header and wire are extremely close to each other and I put some protective wrap on the wire and the wrap melted to my PS headers. How would I go about getting that melted plastic off my #5 header tube? How would I go about pulling the wire back out of the way. I will get some pics shortly. All comments and suggestions are welcome and appericated greatly. Devin

HONESTLY.. that plastic tubing you are using is pointless.. why do i say that ? many many years ago when i got my car and did the first tune up i did not to "protect" the wire. it does nothing. What i've done is while under the car, i have used a ziptie to hold it closer to the head. I never had a problem after doing that. Here in FL 6 years ago or so when I decided to do FULL exhaust ( long tubes and 3" custom dual exhaust ) i did that. I just swapped everything again due to an optispark swap. When i pulled that wire off, i had no damage. Just get under the header and work some magic. it can be done. good luck. if you need specifics just PM me.

#5 has always been an issue for our cars with headers...Before I went with an OTVC set up I used to get a long wire and go up and over the valve cover and back down on to the plug. I used a rubber insulated metal clamp on one of the valve cover bolts as a loom and it worked fine for years...

I have done the #5 around the brake lines and back over before. It did not arc so I left it that way. I soon bought a Delteq but am currently using OTVC wires.

Blk97z28- I told you on your thread when you posted pics of your header installation to make sure all your wires are away from the headers!!! lol

go to autozone and get the accel heat sleeves. you usually use them for OTVC setups, but you can use them on the stock routing.

But they're only about 5" long. I think you can get longer lengths in Summit.

mine were about 8". they have 2 sets. these are plenty to cover from the boot to the top of the valve cover in a curve.

I used msd super conductors and accell heat sleaves. I then went under the car and used zip ties around oil dipstick to pull wire back from the headers. I hope this helps, I know how much of a pain that #5 wire can be. Good luck!
