How many miles on the bike? Could be (and hopefully is) just the CCTL needing replaced. When it wears out, it allows the cam chain to have slack that sounds a bit like BB's rattling in a can...

I did not get quite to that mileage with my F4i but, by 30k, I'd changed mine twice. Not too hard, just a really tight working area...

Rattling in the case isn't something you want to ignore, and changing out the tensioner/lifter is probably the cheapest/easiest first step, so that is where I would start.
