Yup, that's the PVC Valve

I would recheck all vacuum connection to and from the intake.

Also make sure that the brake booster connection is tight. Hose runs over top the PCV valve into the large black plastic "bowl" on the firewall (drivers side). Some mechanics will pull this connection out when replacing ignition wires to give them more access on the drivers side plugs.
