AND, as I learned with my old 4kW, that constant pressure fluctuation can
wreak havoc with the oil pan: Mine developed a hairline fatigue crack
along one of the bends on its bottom. I brazed it up and eliminated the
leak, but it hasn't been run more than 50 hours since then so I've no idea
how long that will hold up.

If you develop a mysterious leak from the bottom, you may want to check for
that.

Hmmm...occurs to me that's a pretty big loudspeaker cone -- wonder how much
of the Onan noise comes from there? :-)
