Default Water in our oil, or just alot of hot air?

If the goal is engine preservation without flying, what would you think of
using a pre-oiler (electric oil pump) to pressurize the oil system and then
pull the prop through several blades every couple of weeks?

Would that keep all the internal parts from corroding, or will some parts
remain dry if the engine does not turn at normal operating speeds?


Any container with a small opening will act as a water pump over time.
During the day, the container will warm up and push out the air inside
it. As the temps drop in the evening, the container will cool and pull
in air. Since it is evening, that air will be laden with dew. The dew
will collect in the bottom of the container.

In the morning the process repeats, except the air is pressed out the
top...leaving the droplet of dew in the bottom. If something doesn't
occur to get rid of that droplet of dew, another droplet will be added
the next night..and the next...and the next.

Adding to what Dan said, when the fuel does burn, it will push H20 and
CO2 past the rings. That's a neat mixture. It was used as an
antiseptic around the turn of the last century. It's called carbonic
acid, I believe.

This is by far the hardest lesson about freedom. It goes against
instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
