I sure freaking hope so. It randomly went away yesterday. Starting again this morning and then immediately went away. RonD suggested I pull the accessory belt. I just haven't had time. I meant to do it last weekend when I changed the oil but I simply ran out of time. Plus I can't hear it when its in park. So hopefully I'll be able to tell when spinning everything by hand.
It's been driving me mad.
Thanks for the suggestion.
