Fuel rail threads touchy?
Hey all, i had a leaky injector issue which turned into a big fiasco. Not that big, but a lot bigger than just replacing the O-rings shoulda been!
At first, i took it all off, looked at my O-rings, they were kinda chewed up...so i ordered new ones. In putting it back together i noticed that the 3 bolts that hold the rail on with those green stand off bolts were just turning and turning? I was torqing them to 9ft-lb? So....i figure I had better take them out and see whats up....well i couldnt! They just turned either direction without tightening or loosening? So long story short i had to get them out with a center punch. I had noticed that the front most bolt (into the intake manifold) was showing a little signs of stripping, tapped it and was fine)
So, i ordered new hardware (3 bolts, 3 nuts) and last night was putting it all together, those went on fine. Now....i had taken the FPR off the rail with those 2 10mm bolts, and when putting it back in, i had kinda the same issue on the right bolt! I felt it right away and backed it out and there was aluminum ALL over the thread on the bolt! It didnt go in that far so i was able to save it and tapped the hole.
I've NEVER had issues like this before, is this just inherent to the metals used in this system or do you suspect someone at one time had installed just whatever nuts and bolts they had laying around? obviously the rail is aluminum...maybe the bolts are too hard?
I am always very methodical and dont rush, not sure why this happened? Anyone else?

Yea...im thinking whoever put this together at one point used the wrong bolts or something?
I didnt even get to where I started to feel the bolt tighten before i knew something wasnt right.
I suspected my situation was not normal, as ive never heard of these problems before.
