[Vwdiesel] Exhaust manifold studs

[Val Christian]

Wow, usually the problem is getting exhaust parts apart!

I don't know of a Locktite or similar product which works at 
those high temps.  In fact, heat is often used to free locking
compounds.

If it's the nuts falling off, I'd suggest safety wiring, or cotter
pinning the nut, to prevent backout.

if you can't get safety wire nuts, just drill a very small hole through the stud, and run a small cotter pin through the stud, preventing the nut
from backing off.
