You may be losing a lot of oil through the valve stem seals.
On my 1974 240D I am losing about a quart every 100 miles which is unacceptable. I drive 40 miles a day and that's way too much. I used a ebay oil separator with 1/2 inch nozzles attached to the catch can which routes the CCV line to the can and then back out to the intake manifold which aspirates the oil back into the cylinders. It separates a fair amount of oil but I can't tell how much since the dang catch can isn't sealed properly and it's a greasy mess.
The post 1979 cars have a cyclonic oil separator which has an air in and air out with a drain at the base. Your car doesn't have the proper manifold and mounting to allow for the return oil line to the oil pan. You can rig up a catch tank and periodically empty it.
