Nology wires melting to plug?

[Porsche_911s]

In some previous threads I read that come 911 owners had Nology wires melting to the plugs.

I picked up a set off EBAY and was wondering if there was a way to try and prevent this.

Do you think the heat came from the plug getting too hot?
If so, would lithium grease help out?

Do you think the heat came from the engine?
If so, would a thermal wrong or thermal tape on the outside of the plug wire help shield the heat?

Any suggestions would be great..

Anyone?

I guess my question is: did the boots really melt to the plugs or did they just stick like spark plug boot are likely to do? If the boots actually melted, I don't think anything you coat the plugs with will actually help as there are some other mechanical issues. Spark plug wires will stick to the plugs or distributor cap on all the cars I have ever had.

For several years now I have given each sparkplug boot a little shot of spray silicone lubricant before attaching to either the plug or the distributor cap. If I remember to do this, I can almost always get the boots off without too much trouble. You could also try a small amount of high-temperature silicone grease, but the spray stuff has worked for me.

Stephen,

Lithium grease is not the product of choice to use on electrical connections, whether ignition-related or not!

Government choice for avaiation applications since WWII has been Dow Corning #4 ... the 'original' silicone grease, and still the best!

Well I learn something everyday! I use a Dielectric grease and perhaps I am mistaking about what it is composed of. I do see what you are referring too Warren.

Dow Corning DC-4 Compound

A grease-like silicone material which provides a moisture proof seal for ignition and electrical systems. More water repellent than waxes. Effective from - 70F to 400F. A low-loss dielectric. Meets spec. MIL-I-8860.

I double check what I am using.

Thanks!
