Default Re: Anti- sieze on NGK TR55 plugs

I use this in aluminum heads.

I understand the anti seize because of 2 different metals, but I thought that it enhanced poor grounding of plug to head. Maybe I dreamed it.

In theory maybe but there's plenty of metal to metal contact at the gasket area.

Interesting theory....
Since spark plugs operate at a very high voltage 40K volts or more?...but very low current something measured in miliamps . A very small contact area with the head should be enough grounding....In theory...would like to hear more on this ...these plugs have a tapered seat and no washer to compress. When the seat hits the head...thats it..they dont really turn after that. I dont see how they can be over tightened without causing severe damage. So im going to theorize (again) that the plugs were so hard to get out because they have been in there awhile, and no anti-seize was used.

You saying taper seat plugs on aluminum head? Didn't think that was possible.

After ripping the threads out of my alum head from a seized spark plug, I'm not inclined to put in a plug without anti-seize again. Incidentally, happened at a divisional race 1000 miles from home so not the most opportune time for it to happen.

Taper seat plugs are what we use on our LT1 and LS1 aluminum heads.

I wonder if this is made differently from normal Anti Seize products ? I worked in the food manufacturing business. During our maintenance training seminars they explained to us that never seize is loaded with very fine ground up glass. The glass wont rust, that's how it won't seize. We had Food Grade Never Seize, in which the glass is ground up much finer. It doesn't work as well as the standard, but federal regulations mandated food grade ( We made breakfast cereal.) Also, just for information,we had some guys trying to use it as a lubricant, like putting a dab on a new seal instead of a grease or proper lubricant. Its abrasive and should not be used for that purpose.But what I'm wondering about, is how much of an insulator do you think this seize creates? The plug grounds through the threads right? It would have to be giving up some continuity and possibly change the heat range in the process? ...

Jeff,

Yes, its composition is different than Never-Seize. The Champion 2612 is a Graphite based lubricant.

The chemical composition of anti seize lubricants is extensive and it is based on the final use and application. I have never heard about ground up glass, however, many of the anti seize products contain metallics. FDA/food approved anti seize products are chemically inert so they would not react with oxygen, chlorine or water, and do not contain any metallics. They are based on fish and mineral oils.

As long as you use a good high temperature Copper or Nickel based anti seize, that does not contain Moly, the heat range will not be effected and you will still have proper grounding and continuity. Most of the products I recommended have at least 25%+ of Copper or Nickel metallics in its formulation,
