I am going to be installing a catch can once the weather warms up to get some very accurate figures ( and prevent the oil from being burnt )

Have you replaced the CCV's on your 4.8? If so they should be the newest design and you shouldn't be burning oil from that, and they are dirt cheap and easy to replace compared to the complicated M54 system.
If you have replaced them and are still burning oil its your valve stem seals.
