I like these ideas and it sounds like it will work well to protect the cam and lifters that are exposed to crankcase air, but what about cylinder bores? Are there any ideas on how to keep the jugs rust free?

Black Max claims to.

I would like to see a picture of @DonMuncys dehumidifier.

Take a look at my album, under the heading "album". That picture is not very good. It is labeled "Dryer". It sits on a wheeled platform. The compressor is much much overkill, but it has been running well over 10 years. Let me know if you need any details.

Does anyone do anything to prevent moisture intrusion through open intake and or exhaust valves? Exhaust purge seems like it would be a lot easier than an intake purge.

I think that virtually everyone ignores drying the air inside the cylinders. Probably because depending on which valves are open and closed, it would be a REAL job to assure drying all the cylinders all the time. Some folks talk about seepage past the rings, which I think is wishful thinking at best. Perhaps because the crankcase volume is larger than the cylinder volume, it isn't so critical. In any event, we do what we can within some economic reality, and hope we are making a difference.
