pcv valve/fuel filter...where are they?

[my name is mud]

I cleaned my upper intake too a while back, I had it off mainly to clean the egr plate/passage and check the vacuum lines and fittings(some of the many things I tried to fix a surging idle before I learned about the 10 pin connectors), But yeah it did seem to run better after it was cleaned up, its nice to hear someone else say it, now I know it wasn't just my imagination.
