I have some exhaust mani studs I need to install. I have antiseize, should I apply this to the part of the stud that goes into the head? Or lube, or loctite? Sorry for such a simple question.

More basic, what is the best way to install a manifold stud? I understand the double nut trick, but how far in should the stud thread in? It shouldn't bottom out, right? Does one need to chase the threads on the stud?

Thanks!

I always use Loctite and install them until the threaded part in the head is completely screwed in. I use the double nut trick also. No need to chase the threads unless you bugger them.

loctite on the stud, anti-seize on the nut. When I was doing my turbo install, I pulled out two studs that were inseperable from the nuts.

Why does the stud need loctite?

The stud needs to stay in , you can use graphite on the nut, it won't burn off.

Thanks for the info. It really helps.

I have some unknown blue loctite in the garage, (label is unreadable now) but it has been subjected to temperatures well below freezing - is it ok to use?
