A positive crankcase ventilation (PCV) valve includes a tubular body extending along an axis between a first end and a second end, the tubular body having an outer diameter and an inner diameter defining a wall around a central passage that extends through the tubular body and is orthogonal to the axis, and a metering device secured within the central passage adjacent the first end. The wall includes a window between the metering device and second end, and the window defines an air flow path through the wall and into the central passage for detecting a disconnection of the PCV valve from the crankcase, wherein a total area of the window is greater than an open axial area within the metering device when the metering device is in a maximum flow condition.
