Bad head gaskets generally leak coolant, not oil.  (Well, that's not
necessarily true on diesels, but it is on Wasserboxers.)  I bet if you
look closely, you'll find that the oil is leaking from under the valve
covers and running down to the bottoms of the heads.

A set of valve cover gaskets will cost you maybe $10, and you can put them
on in 15 minutes.  Maybe 30 if you really have trouble getting the valve
covers off.  This is an easy repair.

Fix the leak first, then switch. :)
