So is this necessary? I was always under the impression that it took away power, and it sucked acidic fumes into the intake. But lately people have been telling me that this is the only good emissions device good for the engine.

Any power loss by a PCV valve is going to be negligible and overall the effects are better because the engine moisture is pulled out and burned.
