My truck has two holes in each valve cover, so I have two oil filler holes and two for the PCV system. They are painted Chevy orange but are green-blue underneath, so they might be off another car. The hose connecting the air filter to the valve cover is not a good thing, my air cleaner fills up with oil if I don't check it enough. Anyway thanks for the input and the rundown on the whole PCV system, it helps to know how things function.
