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?
