For the engine mounts, the upper ones use nylock nuts. I use blue loctite on them as well. The lower mounts (foot pegs), I use blue loctite on. The back engine mount.. I have never taken it off.
Things said in various places about using oil on threads:
================================
http://benmlee.com/4runner/threads/threads.htmTesting Conclusion:
-Threads lubricated with 10w-40 oil gave the most consistent results.
-Placing 10w-40 oil on threads does not change the bolt tension.
-Threads with anti-seize paste added to it has as much higher tension (Up to 71% increase) than with dry threads. That extra tension could conceivably strip out the threads. This could be the reason why spark plug installation specify that a 3/4 turn after seating rather than a torque value.

down on its respective stud to be sure
threads are clean and free of contamination.
Place a drop or two of oil on threads of each
head bolt just prior to final assembly.
NOTE - Light coating of oil on head bolt threads
minimizes friction so torque values will not be
distorted.

From our very own OldFeller in this thread:
http://suzukisavage.com/cgi-bin/YaBB.pl?num=1256079122Yes, there is some stress taking one (1) loose, but less stress than taking all 4 loose by far. YOU MUST LUBE OR OIL THE THREADS OR YOU DO NOT GET AN ACCURATE TORQUE READING AT ALL -- all you get is twisting of the stud and jerky erratic movements from the fastener rubbing on the copper washers.
