what PCV valve are you running? any check valves?

I don't know for sure about the PCV valve but I probably bought it at Auto Zone. Should I replace it? I don't have any aftermarket check valves. I have the stock fabric hose from the MAF to the turbo. I looked at it and couldn't see any rips. I thought about placing an incense stick under the MAF hose to check for leaks, like the smoke machine.
