Rod bolts fell out!

I would not loctite rod bolts or nuts. Usually the rod bolts are pretty tight in the rods. Rod bolt/nut assemblies also differ in weight. As long as you can,t push the bolts all the way in with your fingers I would leave everything as is and reassemble it torquing everything to spec. Good rod bolts usually have identifying marks, some even have machined dimples for measuring stretch.
