There is a small auxilliary filter in the air filter box fpr the PCV system. It connects to a hose that goes to the driver side valve cover. If the PCV craps out this filter will get oil soaked and fall appart. It is available at most any parts store.
Thanks BERATTE,
I thought there was no PVC Filter.
I traced the one hose from the PCV valve, to the Upper manifold.
Also I traced the other hose from below the oil filler cap, to the mass air area.
The flow of air must be, from the mass air area, to the filler cap, through the crankcase, and up through the PCV valve, then into the upper manifold.
Thanks,
Gene
Yes, I agree with you on the routing. I replaced my PCV valve a few months ago and went on the same search you did and finally concluded there was no filter.
