Mine is on the front valve cover with 1/2" rubber hose attached to it.AnswerIt is in the intake manifold. There should be a hose going to the throttle body from it. AnswerWhen you replace it, be very careful. The rubber grommet on mine fell into the intake when I pushed the valve in. It is not easy to remove.
I'm not exactly sure who said there was no PCV valve and that it came out in 95. What an idiot. There has been some sort of PCV valve system on vehicle engines for decades. I'm sure someone may know better than I, but I think the last engines made without a PCV valve were the old flat head engines built in the 40s. There is most definitely a valve on your engine. It is on the rear valve cover towards the driver side. It is a little difficult to get to....and to get out....but I assure you it is there.
It is on the top back of the engine; there is a 3/4" rubber hose coming from underneath the air intake plenum/manifold that connects to it. Unless you have very small hands you will need to tilt the engine forward to reach it.
