Patrick,
Also check the front pulley, ad locking washer key way for wear or a crack.
I had one doing that once and at low revs the front pulley was sounding like
that with the key. The front pulley nut had come loose, wiping the keyed tab
off the locking washer and allowing everything to come slightly loose and
chew each other.

My guesses?
If it's a click, not a rumbling noise, and you have oil pressure and
it still drives, then I'd guess a worn out little end and/ or a worn
out cam lobe and follower.
