I'll have to keep this one in mind, seems as though this is happening for a lot of people too.

A piece of 3/8" fuel line or a hunk of heater hose also makes an excellent stethoscope. It fits nicely into confined areas.

If you have a prybar or a long screw driver those work better than the cardboard tube trick. But if you don't it's not a big deal.

While your under the hood, check everything. Tensioner, idler, water pump, etc.

A bearing in a waterpump or tensioner/idler will have a deeper growling noise that varies with RPM
