The few things I've heard about causing the problems a

Flying too infrequently, with oil seeping off the cam and moisture eating
at the exposed surfaces.

When flying happens, not getting the oil completely hot, so as to
eliminate the moisture from it.

That's one thing that could be changed on aircraft engines that would give a
LOT of bang for the buck - positive crankcase ventilation. Huge reduction in
unburned hydrocarbons (you may or may not care about that), and a lot less
moisture in the crankcase - engines last a lot longer.

The straight up auto style PCV valve probably wouldn't be the way to go,
though. It won't get you much at higher altitudes where you have the
throttle wide open.

Running the engine too slow at startup. Apparently, the cams in some
engines get lubrication mainly from the oil splashing around inside the
case. In some engines, 1000 RPM may not be sufficient for full
lubrication after startup. My A&P suggested 1100 - 1200 RPM.

Anything's possible.
