It is normal to get some oil in the breather hoses as it's carried by the
vapors.  If you rev the snot out of the engine then you'll get a lot of oil
in the air filter.  That's what the baffle prevents.  I remember when we
were putting together a old '78 Rabbit (Golf) as an SCCA Improved Touring
racer years back.  We had not set up a catch tank for the oil blow-by yet
and just had the stock plumbing for the breather hoses.  After the 1st track
session we brought the car back to the paddock and popped open the hood.
Boy was there a sh*tload of oil dripping from the fuel injection box.
Pulled out the air filter and it was thoroughly soaked with oil.  We put in
one of the then new VW camshaft oil baffles and it solved that problem.
