SCAN your car and go from there tehre might be some stored codes.

BTW, teh sound in your video is NOTHING like the one of OP. Two completely different sounds/noises.
i scaned the car few days ago and the only engine code that i got was a thermostat failure (bad electronic control of thermostat that causes 10ÂșC higher engine temp than normal).
this rattle can be caused by old spark plugs? loose post-cat sensor? (pre-cat are tight). bad exhaust valve timing? (bad vanos seals) or what?
i will check all this things and ignition coils.
i think that the background noise (knocking like "tac-tac-tac") is the same in both videos.

and what can you say me about alternator whining? it's a really loud noise that kill the L6 sound of this car

thank you
