Well idk about a Cali car, but GTO's don't have a pcv, they just suck up vapor full time, which is why catch cans are very popular with them.

No check valve. Check the routing of your PCV hoses to make sure they are correct.

Oil in intake is normal.

As far as burning oil, if the engine isn't leaking from old gaskets or seals or your crankcase vent system isn't fubar'd somehow, it could bea worn rings or valve stem seals.

GTOs do have a PCV. They just don't have a serviceable PCV valve. The PCV baffling is built into each valve cover and the valley cover. Adding a catch can simply provides an additional filtration between the valley and the intake manifold, and it does help immensely.
