    I agree, some of them develop issues. Lycoming recommendations are worst case scenario. I wouldn't call Arizona worst case. Know your environment.

    But don't heat the bottom to make steam that condenses on the cold top and cam.
    Just keep it 10 above dew point.
    There is no dew point in southern Arizona, what is a dew point?

    It might drop below dew point in the evening from heat radiation out to the night sky if parked outside or perhaps in a hangar with a metal roof.
    Even in dry country, if you run it only a few minutes the moist combustion gas gets past the rings and into the crankcase. I think it was Piper that tested periodic short engine runs for storage and found it to be worse than no periodic runs at all. The oil needs to get hot.
    The upper surface of any tank tends to collect dew. My tractor diesel tank gets wet on the inside of the fuel cap.
    I suppose the same happens in a crankcase. I wouldn't worry about it. I do nothing here just 400 feet from the pacific coast.
