I have a 1994 Nissan Maxima that I have had since 1996. It has 217,000 miles on it. It has 6 ignition coils that sit on top of each plug. Three of the coils have developed cracks and they are occasionally arcing out to the valve covers. Since I am a cheap sob, and the car is old and high mileage, but definitely not ready for the scrap yard...what can I do to fix this without having to buy new coils at $170 each...aftermarket.
Is there Anything that I could fill the cracks with that is non-conductive that will keep the electric charge contained? I have tried putting electrical tape over the cracks but that doesn't work well.
edit; I was thinking JB Weld, but the package says it has metal in it.

My first thought was a cheaper wrecker, I have a place things like this are one price, and might be $10 each.
How much eletrical tape did you put on? It must be enough to insullate, like 1/8" +
How about silicon caulking?

They made that engine for years, I would think you could find some salvage yard replacements.

If you've got the SOHC engine, the Autozone price here for those coils is $41.99 and they're in stock. For that price, I would replace them - anything you try to fill it with will most likely come out.
That being said, I would probably try a 2 part epoxy after a good cleaning and drying of the crack. The filler used in them from the factory was probably something like this.

It is the DOHC engine. $170 each was the price O'Riellys quoted me. I see AutoZone has them at a more reasonable price....$60. I will still try a cheap fix first. |

What about silicone tape? I keep a roll of it around. It is self-fusing tape(it sticks to itself), so you would just wrap it tightly around what you are trying to seal. It is thicker, and stronger that electrical tape, and might be worth trying. I use it for a lot of electrical applications, and never had a problem with it. It is a little tricky to work with, but works great. http://www.rescuetape.com/ |

I too would try the salvage yards first,, I'm sure those coils are used on many other models and there should be a few around to be found.. Other than that I'd also try the epoxy..

Coils go from worn plugs close the gap on the plugs a bit and make sure they are in good condition plus maybe a little silicon gasket seal would do the trick. But I would also replace the coils. If this is the one you have I can get them for 125.00 ea   |

I am going outside the box here, but are the coils cylinderical? If so have you thought about using PVC pipe as a sleeve? A length of pipe may be a cheap fix while you are looking for replacements.
