Have you checked the lash of the timing gears ? Anything more than about .009" and they'll rattle. Yours don't look very good from the picture, but, checking the lash is whats needed.

Running the engine with the timing pin inserted and putting pressure on the gear is sometimes a good way to determine if the gear is bad/worn.
I ran with the side cover off and it sounded to me to be coming from the front of the engine. That's what led me to pull the timing gear cover. I will check the lash.
