   weakened the threaded connection by applying too much.  But if I'd applied
   just a small spot, it too would have been smeared over the threads and
   might not have been as strong.  Yes, I'm over-thinking the problem.  But
   what say y'all?  What's the preferred method?

  I will not say that this is 100% correct with all of you experts.  I have
  used Locktite on rod bolts for years.  My machinist told me that he just
puts a
  little engine oil on rod bolts while building stock car engines.  He says
that
  it is the torque that holds the bolt in the hole, not the Loctite.

  I am now not using Locktite.  My reasoning is that you better torque the
  bolts right away, or you can get a false torque reading.  Also, when you
change
  out the rod bearings, it is almost impossible to clean out all of the dried
  Loctite, which will also gives you false torque readings.

  If you are installing Carillo rods, you are told to use their special
  lubricant on the threads and under the bolt heads.
