Just looked at my mates VZ SS to see the difference to my VY SS PVC and his because i am told the VZ is different to the VT-X-Y. so me has a look see and find it has nothing at all, just a crimped end to the passenger side rocker cover and on the driver side cover nothing, it just has a hose at the throttle body running back to the throttle body.
So the driver side must be plugged of as well but i can't see it with out taking the plastic cover off to see.
He has owned the car from new and says he did nothing at all to it.

This can't be right ! just blocking them off ? i should of just done that to, instead of forking out $120 for a new PCV, as his works just fine block off.
