Default 2000 OBS (2.2L) PCV valve?

Does my engine have PCV valves? I was looking yesterday to see if I should change them or not and it looks like the hoses just go straight into the valve covers. Are there PCV valves there under the hose?

Also, what is the third hose going into the airbox coming from around the throttlebody area?

Thanks!

The PCV valve is in the intake manifold. It's the black fitting with the hose on it.

The other hose should be for the IAC (idle air control). It's just a throttle bypass for the idle, and the the valve on the manifold is opened and closed electronically by the ecu.

Part of the crankcase vent system.

ok, this might be a stupid question, but isn't the crankcase venting system the PCV system? If I get a catch can or just vent using breather filters, which hoses should I use?

Take off the air box and the intake tube, and it is on the rear of the intake manifold, just left from center. Disconnect the larger hoses one by one until you find the Pcv valve.

ok, I understand where the PCV valve is now but what can I do with those two hoses coming from the valve covers to the airbox? They're putting oil into the airstream as well. Can I just vent them using breathers?
