The rails snap into place and are thererfore hard to install wrong.

This could be a cam sprocket not parallel to the intermediate shaft, but that would be a noticeable noise as soon as the motor was started (after a rebuild or cam work) and then shut down to investigate. A situation like this should never arise because some binding/resistance and noise would occur when turning over the motor by hand as you were doing the repair work.

Those spots in the green circles are where the chain bounces off the chain housing and ramp when a tensioner goes down. Otherwise known as the "chain dragged out of a metal garbage can" sound.

If your car isn't making that sound now, i'd have to think that picture is previous damage. Not something happening now.
