PCV vacuum

I took out my rats nest and hooked up the old purge valve.
I'm thinking of switching to a PCV valve, but not 100% sure how to hook it up.. Can anyone get me a pic of a successful PCV valve setup?

Thanks

The valve is from an early 90's dodge caravan. As for the direction it goes- blow in one end, if air goes through it, than you want that end plumbed into the oil filler neck, which goes into the "crankcase". The other end goes into a source on the intake manifold.

Works for me, but I have an SA. It could be different for a FB, but I doubt it.

I guess in ours it should be called a PEV valve instead

What's wrong with the purge valve? It does the same thing.
