95 Buick LeSabre 3.8L

Would someone please tell me where is the PCV valve is located?

It’s located on the lower intake manifold below the upper intake plenum at the front of the engine. It’s not easy to get to or to change. Stand in front of the engine and look on the left side of the lower intake manifold below the upper intake plenum. It’s in a nook of the upper intake plenum.
