Blue smoke, definitely oil smoke. It only does it after sitting overnight, if I restart it after fueling or stopping for a few minutes, there's no smoke. It's not using oil that I have noticed and runs normal, not down on power at all. My thoughts are rings or valve seals.
That's a valve guide seal problem. It could be that the valve guide clearance is too large, which means new seals wouldn't last very long.
