On A Volvo S60 What is the foam encased part called that is behind the intake manifold and has hoses to the crankcase and head and intake manifold?

The part you are referring to is called a "Flame Trap" - it is part of the positive crankcase ventilation (PCV) system. When it fails it causes too much suction in the crankcase, usually resulting in a nasty squeal or howl at idle that goes away when you remove the oil filler cap. Replacing it requires removing the intake manifold. My dealer quoted $450.00 for the job ($100 for parts and 3 hours labor).
