I can't quite tell from your clips.

On my 3.2, I've occasionally encountered somewhat that kind of sound. Mostly at low RPM, idle and a bit above. Really worrying, couldn't pin it down, then it went away. It has come and gone several times over the years.

The best I can think is the hydraulic timing chain tensioners are ratcheted. Maybe as they approach the next tooth, the chain is loose enough that it slaps a bit. Then tightens back up as the tensioner advances.

I dunno, does this make any sense for you? Or, can anyone chime in on my case?
