Greetings all,
I am not understanding on the torque question, in the case where
Never-Seize (or equiv) is used. If used, on something like manifold studs,
are the specified torque numbers still correct?
When I put my manifolds on a year or so back, using a torque wrench, and
N.S. on the studs, I did have problems. On one or two of the fine-thread
studs, the nut "jumped" the threads just prior to reaching spec, and then
would not tighten to spec. I ended up having to replace the stud and try
again. These were the "bronze-looking" ones, which I assume have a softer
copper (or?) plating on them.
I assumed that what might be happening was that with lube on the threads,
the nut was actually getting tighter than it should, compared to what I was
reading on the wrench. And so, I was actually over-torquing even though
the wrench was reading "ok." If so, I guess the best answer is "don't use
N.S. on the threads?" Or is it possible I just had studs with
poor-tolerance threads? Wonder how the real engine jocks handle this....
Thanks!
