The stock Miata PCV valve allows full boost pressure to flow into the 
crankcase.  The correct valve comes from a turbo 323 GTX and is not available 
at most FLAPS  (their cross-reference charts show the wrong one) so just get 
the right one from FM.  To test one just blow through it in the direction 
toward the valve cover.  It should completely block air flow in that direction.
