The weird thing is that the noise came from the rear passenger side, while the bolt I took out was in the front driver side. Maybe loosening the one bolt caused the manifold to pull up a bit at those rear bolts and the intake gasket came loose as you said.

Thanks! We had a good melt yesterday, but this morning is another torrential snow fall. So we'll see how high the snow gets on the hood again by the time I get home from work.
