Wow! That is major, hard to believe that this was triggered from a balancer. Worse thing i ever got from one going bad is a gouged up timing chain cover along with really violent engine vibrations when it failed. I just came from the junkyard about an hour ago and seen an endless number 5.0 rollers (exploders as well) so all isn't lost. At least you don't have major block work done. Just scope around. :thumbsup:
