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).

Can the head gasket be blown and not have water in the oil crank?

Not likely. In fact, the backyard mechanics' test for a blown head gasket is to drip some oil from the dipstick onto the (hot) manifold. If it bubbles, there's water in the crankcase. Another sign is white smoke in the exhaust.

What is a PCV valve for?

Positive Crankcase Ventilation Answer 2: The Positive Crankcase Ventilation (PCV) system reduces hydrocarbon emissions by scavenging crankcase vapors. It does this by circulating fresh air from the air cleaner through the crankcase, where it mixes with blow-by gases and is then rerouted through a PCV valve to the intake manifold. - Haynes Repair Manual #36071

If you don't vent your crank case in your Chevy sb will it cause coolant to go to your crankcase?

No, but your crankcase should be vented anyway. If your getting coolant in the crankcase it is getting in from a bad head gasket or cracked head or bad intake manifold gaskets. If you don't fix it soon your engine will be toast.
