Could you tell me where the PCV valve located?

Could you tell me where the pcv valve located on a mazda b 2300 1994 2.3 liter.I have looked everywhere. Is it located under the intake manifold and if it is how do I get to it without taking off the intake manifold itself? PS I can see a vacuum line from the evap canister going under the intake manifold but I cant get to it. Thanks, Steve
