    Today did the test again.
    Cold start, smoking atleast 15 min while idling, sometimes smokes automatically, or sometimes I have to hit the throttle to start smoke again. After that, I use it nearly 5 min, then I did a test for the valve stem guides, I went to a descent road, going down holding 2nd gear and no smoke, after that I drove 10 min more and let idle a few minutes again, no smoke, I hit throttle, no smoke, so everything looks good about the "smoking problem"

    As I said, I will replace the PCV valve and will improve the vacuum nipple of the intake to be sure and avoid problems in the future, relocating it closer to the turbo. Still have the AFR problem and the strong smell/flavor to gasoline/petrol in the rocker valve and my opinion is that is not normal, I can't think of any more options than an injector is leaking.

    I removed the oil dipstick, smelled the oil, and there is no gasoline/petrol flavor/smell, only in the rocker valve and oil fill cap.
