The PCV on the 2.0L Zetec is under the exhaust manifold. If you look at the thermostat housing, there is a steel hose that runs underneath it. Follow that down under the exhaust manifold. It can be changed if you know how to do it with out taking off alot of stuff.Depending on flexibility and hand size, the average person can reach the PCV from underneath the car. Reach under the exhaust manifold, between the catalytic converter and block - PCV is in plain view from here. Otherwise, you'll have to remove the heat shield above the manifold (horizontal across front of engine below valve cover) and catalytic converter from the block as outlined in the Haynes repair manual.

just remove thermostate housing and there is a bolt holding the meatal tube going to the pcv. need 10 mm and a 3/16 Allen wrench
