Or if someone else can post the videos, I can email them the videos. That way others can listen an see if it sounds like the same problem.
They are large files so I don't know if that's a problem for email.

Based on comments here, it sounds like running the engine with a bad chain tensioner may not be a good idea. I'd like to try holding at 1500-2000 RPM under no load to see if that may free a stuck lifter, but I only want to try that if there is low risk of doing damage as a result of a chain tensioner issue.

Would a tensioner tend to seize or bind up after sitting unused for a while? My first instinct was to blame a lifter, since they can bleed down and wouldn't pump up again if their check valve were frozen.
Does anyone have a recording of an engine with a bad timing chain tensioner? The noise in my car definitely sounds like valvetrain clatter, and as people have pointed out, it is timed to the camshaft speed.
