To "anti-seize" or not, is the question.

There are two kinds of people in this discussion; those with seized and galled fasteners, and those that used anti seize..................

Hello JFP, speaking of anti seize..
I always put a very small amount of thee grey anti seize it on the spark plug threads (have don it for many years with the aluminum heads) and never had an issue with this practice, but I remember reading somewhere that on the plugs you should only use copper anti seize to help maintain a proper grounding, what do you use for this application?

Any metal based (silver aluminum, copper, or black nickel) will work just fine. On any high temperature application, like spark plugs. we always used nickel due to its excellent high temp properties.

Thanks JFP! I bought a can of black nickel anti seize about 20 years ago and still has a lot of paste inside..

On applications like spark plugs or exhaust manifolds, it cannot be beaten. And I have no idea how old mine are, we buy stuff like anti seize or PTFE thread sealer in the largest containers they make as just about everyone in the shop is constantly reaching for them; they are consumables like shop towels or toilet paper, and like them never go "out of date".

On caliper bolts?
I question because I never heard of it.

Decidedly on caliper bolts, one area where tread stripping or galling due to dissimilar metal reaction is a common problem......

Thank you for confirming. Does Porsche recommend its use on steel in the service literature? I am surprised to see it not used in production. My Porsches are original and most are low-mileage, so they are as they left the factories. I just want to know if factory torque values are given with anti-seize on threads or dry.
