Noise on cold start... Please help...

I am having some trouble. I am a new diesel truck owner. I purchased an 08 F450. Has been running great untill recently.

I have noticed a few 3-6" long pieces of my serpentime belt under the truck as well as some serious "ball bearing" noise when I start cold. It goes away after a few seconds, but it's loud. It sounds like there are marbles in my engine block... Any idea what this could be?

Thanks,

Jason

Sounds like maybe the belt tensioner is coming apart to me
