Question about Cars & Trucks
I would think that if the PCV valve were actually plugged, there may be enough pressure build-up to unseat the thing, which would cause most oil leaking from crankcase pressure to exit via the hole left where the PCV was. Just a guess. How many miles on this Nubira?

Yes there is a PCV valve, you just have to look for it.
Engine may be over full on oil.

Testimonial: "Thank you very much.I will look for the valve."
I have one of these cars too, also 3.5. I purchased with 34K and has used a quart of oil every 1000 miles since then. It has no leaks or smoke or any other signs of oil consumption. So much research, nobody knows why these engines do this, some have gone as far as contacting Chrysler just for them to say, " that's normal". But here is the diagram for the PCV:

No it's either bad piston ring's or bad valve seals, the PCV ( positive crankcase ventilation ) only job is to reduce the air pressure in the crank case, so that it don't get moister in the crankcase like an air compressor.
