My car has been raced and the guy who raced it said it always burned oil. It just is the way it works. If you put a breather on I think oil would just leak out the breather as the pressure would rise and force it out. Atleast that is how I understand it. An oil seperator will solve the problem, rather it is a workaround, and the sperator must be emptied every month or so.
