Hello,

The PCV should be on top of the passenger side valve cover. This is the valve that should go into the throttle body to reburn the crankcase gasses. There should be an inlet on top of the driver's side valve cover with a hose coming from the air intake tube. This incoming air is pushed through the crankcase up to the PCV valve where it is then ingested into the throttle body to be burnt in the normal combustion process of the engine.

Thanks,
Alex
