I'm not a LR mechanic, especially when you consider these modern trucks, but I ran a search for PCV at ABs site and came up with this:

So it looks like you can get something. The usual test for a PCV is to remove it and shake it. If it rattles, it'll let air get by and it's still good. Best prolly to stay away from AutoZoned when searching for Rover parts...
