Usually blocked crankcase breather (not sure were that is on an A/C (all my experience with these vans is with watercooled flat fours)

Also could be worn piston rings and / or bores causing excessive crankcase pressure (more serious but not as serious as if it was watercooled !!) - A compression test would tell you if it was this.

Some folks do a temporary "fix" by feeding the pipe that goes from the crankcase to the air filter into a pop bottle instead of to the air filter housing (to catch the oil but still let the crankcase "breath")

The crank breather on the 2.0 is to the right of the distributor as you look in the back of the vehicle. Its unlikely to be a blocked breather but more the result of excessive crankcase pressure. As the man said do a compression test, could need rings. Is it burning a lot of oil?
