2004 BMW X5 Question: PCV location

Where do I find the PCV valve on the 4.4L? -
Answer 1
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. Zee -
