Wanted to post the follow up after resolving this issue defined in this post: La-Z-Link.
It ended up being a minor bend in the lower timing cover coming into the slightest contact with the belt at the top driver side where it bolts to the water pump. No damage to the belt luckily. All back together and it's quite as a mouse. Thanks as always for the help here.
