PCV location on 2004 BMW X5

Where do I find the PCV valve on the 4.4L?

Asked by for the 2004 BMW X5
They are on the top of the valve cover, there is one on both banks. They are about a 3" diameter round plastic part, the replacement comes with the top, diaphragm and the spring. Replace them in the same time. If the diaphragm cracks / brakes it will suck oil into the intakes.
