    Yes, if you can get it, try; "Marvel Super Lubricant" spray. From the old
    Marvel Mystery Oil company. It is the best penetrating oil I have seen. I
    have used it on frozen valves where regular penetrating oil (WD40 and
    similar) repeatedly failed. Soak the threads in the foam and let stand
    over night.

    WD40 is not a penetrating oil. Not even close. not even a good lubricate.

  6. If its a penetrating fluid youre looking for, you need Kroil aerosol ;
    nothing works as good as this stuff.

    Often, the largest difficulty with oxygen sensors is that the wire
    prohibits installing a full socket on them. My recommendation would be
    cut the wire off the sensor and attempt removal with a deep 22mm socket.
    If the sensor remains difficult to turn after breaking free, use plenty
    penetrating oil and turn back and forth in small increments while
    removing the sensor.
