Does anyone else have a problem with spark plug wires melting with stock exhaust manifolds? I bought the car about a month or two ago, and its already going on its second or third set of wires... Is there supposed to be wire holders that aren't there? Its a bone-stock 1992 Chevrolet Camaro RS, 305 Auto. I bought some Accel wire holders, but they don't help very much.... The problem is worse on the drivers side (when I got the car, one wire on the drivers side was completely melted in half).

Any help would be appreciated.

 

Are you running your wires over the manifolds, or under them?

 

When my 1992 RS was stock, never had any issues with spark plug wires melting in their stock location. You may want to try using a different set of wire loom, get some heat shield made for plug wires or a combination of both. I currently have my plugs above my slp headers. Have not burned 1 yet.

 

Right now they are ran over the manifolds. Sorry it took so long to reply... We are currently in the process of moving, and are staying with my wife's family......

I was thinking of making some, but I wanted some other opinions before I did anything.

 

If I remember my old manifolds, shouldn't some of the wires run underneath???

 

Yes, stock cars had some underneath the exh. manifold

 

I plan to swap to a 350 with headers before too long, I'm just tired of my car running like crap bc the wires keep working their way to the manifold. A guy I work with has a 91 RS, and he said that his mechanic fixed his from doing it... I'm going to take a look at it tomorrow.....

Will the stock wire lengths run underneath the manifolds? They seem a little short.... Unless the auto parts store gave me the wrong wires.....

 

Do you still have your heat shields on the stock manifolds? Those definately help keep the wires from touching the pipes.

The stock wires are cut in lengths to run a certain way to each cylinder. You would need custom wires to run them any differently.

 

No, there are no heat shields on there. When I bought the car, it ran like complete crap, and after the first week I found one of the wires on the drivers side had melted completely in half. It is also extremely hot in the engine bay while its running, like the air isn't moving through it. Do these cars normally run that hot?

 

Just for a quick fix until you get the headers you can use zip-strips to tie them up. put one around all 4 wires to that side, and then another between each wire and around the first zip-srtip. It will help keep even spacing. Then just use a couple more to get the wires to stay in a safe spot.

 

Yep, I use zip ties on my wires. You can get creative with them and set them up to look and work just like a wire loom.

 

Try these from Ecklers.com, I used them for my 89 TPI. You should have two post on the drivers side on one on the passenger side. Look around the engine compartment and you should see them, kinda flat post that these things slid on to. I'm not sure about 92 TBI but I assume the wires should be routed the same.

I had the same problem when I bought my Camaro even with wire looms...what brand of wires are you purchasing? Don't get the cheap ones for like $20, go the extra money and get the ones that are closer to $50-75. I believe I bought the Bosch from AutoZone and they were the first ones not to melt. They have a lifetime warranty on them also, so if they burn out...take them off and get new set for free...or buy a new set, change one at the time (smarter to not get them confused) and then take old ones back and get money back...they do it either way with their warranty system.

 

Doc221978 and Heat Seeker, do either of you have pics of how you have yours tied up? Might be a cost-effective way to cure the problem until I do my engine swap.

kozman, I do have the posts for the holders, so I might have to look into that...

ashley51071, I'm using the $35 wires from AutoZone (I forget the name brand at the moment), but for my next set, I'm going with MSD or Accel wires.

Thank you all for your input.
