Yeah I agree, like stated above when I first heard it I thought lifter noise as well because it does sound similar. Any light throttle will quiet it down so the noise does not increase with RPM. So still leaning towards the fuel line check valve or a bearing. Someone also said the lash in the gears could be off. Either way you can't just close the hood and quiet it down, it is easily heard in the cabin now with the windows up.
I will pull the belt and spin it by hand and see what that yields. I have a contact at a different dealer, waiting to hear back before I take it in and get another "that's normal" statement.
