No PCV Valve???

While doing some general maintenance on my recently purchased 97 LSI this weekend, I went to change the PCV valve and did not find one!!

Where is it supposed to be is a black, plastic "F" connector with two hoses connected to it. There is no check valve in this fitting as all ports are wide open to each other!

One of the hoses goes to the intake, whose port is wide open too!

Open for ideas and suggestions!

Thanks!!
