Positive Crankcase Ventilation Valve: Description and Operation

Taurus SHO PCV System

OPERATION

This system is unique because it does not use a PCV valve.  Instead, the crankcase gases flow through an oil separator to three ports in the throttle
body.  Fresh air for the PCV system is supplied from another port on the throttle body to the cylinder head cover Under various throttle conditions,
the air and crankcase gases flow differently through the ports in the throttle body.
