#2 is the second sound (right at 1:00 - correct) that sounds like maracas that just started two weeks ago.

Both the ticking and maracas sound (lol) stay until the car is warmed up and then I don't hear it again really until the next full cold start. My indy mechanic couldn't identify and I'm hearing others with similar issues. I'm not noticing any driving issues, so I guess we just call it normal at this point?
I'm not ready to call it normal yet Anything involving the potential for the belt to slip off and get sucked into the crankshaft seal is worth continued efforts IMO.

Hopefully I'll get a chance to look at mine more closely this weekend now that I have the belt and pulley kit in hand.
