I don't know! But why wouldn't you use the stuff that has the higher temp rating? In this case, I would think that a little higher is better. I just finished a top end on my /7 and used the nickel based Permatex brand...Snowbum recommends it.

Kurt in S.A.

I have used both with no obvious problems. Mostly I have used the silver stuff.

The base question was about copper versus nickel anti-sieze on exhaust spigot threads.

If we don't know, its ok to say so.

But Primate asked another question. You have to remember, there is no "base question" here. There's a first post, and then whatever the hell happens after that.

BUT, as for your question:

There are actually three main groups: silver, copper, and nickel (silver not containing the metal "silver," but being silver colored), in ascending order of temp rating. You'd think that you'd want the highest temp rating for exhaust, but all the manufacturer recommendations seem to be for copper on exhaust components, while Permatex says of the nickel:

" It is recommended where copper contamination must be avoided, under conditions of extreme pressure and temperature, and with stainless steel, titanium and nickel alloys."

So, my guess is that you want the copper rather than the "standard" stuff, and the nickel would be fine but is not necessary.

Boy, this thread is a disappointment. Lubricant threads are spozed to take off and have a life of their own!

Here, I'll throw a wrench (big brass BMW exhaust nut wrench) into this one:

I use regular old anti-seize on my exhaust threads, but I use Philips' Milk of Magnesia for spark plugs on air-cooled German vehicles. I'll check in again tomorrow. Do not disappoint me!

Yup, I'm the threadjacker--guilty.

As for your question, I've had no problems using the nickle stuff on the threads, and that's an anecdotal fact!

That reminds me, (light fuse) what's better, synthetic or dino oil? (get the hell out)

It just so happens I also watched Chris Harris' video 2 weeks ago and decided to take his advice. I carefully loosened and removed the exhaust nuts (silver anti-seize, which is better than nothing), cleaned the threads with brake cleaner, applied the Cu paste and re-installed the exhaust nuts. Not a single problem or anything to bitch about, but what a bitch that last oil change was!

Did someone mention oil thread???

Milk of Magnesia is a suspension of magnesium hydroxide which is used as an anti seize in extreme heat situations. I think I would want to paint it on then allow the water to evaporate off or flash it off with a heat source.

Did that fulfill your expectations ?

No, it was reasoned and factual. I was looking for the usual poop-flinging!

You idiots are wasting your money on that crap. Just paint Milk of Magnesia on it and it works just as good.

...stupid people....









Better?
