Crankcase Dehumidifier

[Pearson]

Have any of you built something to keep moisture out of your crankcase over the long wet winter? There is an article in this months EAA magazine about how to build one, but it looks really complicated. Winter here in the Pacific Northwest means rain, lots of rain. And it is a cold rain. I am sure my crankcase has little beads of water clinging to it right now. One of these dehumidifiers would be great, but the one shown in the EAA magazine is above my skill level when it comes to electronics. It has a diagram of a pretty complex circuit board to control a purge valve, air pump, and heat lamp. Has anyone seen anything like this available commercially?

Richard, this is pretty straightforward. Might do what you have in mind:

I have a friend that built one that he uses on his Piper. He LOVES it.

Rich, you can order the kit that has all the techie stuff done. At least that is what I under stood. Now I need a solar powered one for my field! Three planes, two hangers, no electricity on the field... Larry

Where do you order the kit from?
