Www.barkeraircraft.com It’s a kit that must be assembled It uses an aquarium air pump and electronic circuitry. It pulls air through desiccant beads and drys the air The air is drawn through the beads, dried, then through the engine via the breather returning via the oil filler cap. Like the desiccant beads in storage plugs these beads absorb moisture and turn from blue to pink as they absorb moisture This kit has circuitry which senses the moisture level, turns on a light bulb which heats the beads driving off the moisture turning them from pink back blue and reverses the air direction dumping the moist air. when they’re dry it resumes the flow through the engine and shuts the light (heater) off It uses a gallon pickle jar for the beads So it continually draws dry air through the engine
We we all know one of the quickest way to dry something is wind or just movement if dry air After a flood in my sisters house I rigged up a barn fan that ran for six months drawing air through the underside of the house and ended up with no mold It works and does keep the engine dry Heat gives rise to condensation And for you guys who thing your tanks never get any moisture, let me tell you, you can’t fool Mother Nature
the circuitry isn’t simple and I chose not to do the circuit part myself I went to my buddy Paul (Wire Winnie) AKA (Web) and had it done right
I have seen a commercially available unit that does sort of the same thing but nit sure where
The engine I recently bought with my new cub project had been filled with oil for a number of years prior to my getting to that part I assumed it would be good factory new, case never split, with 1000 hours The cam and lifters came to 1800$ and the four new melinium cylinders were about 5200$ It pays to protect the engine
i should add that I use Pickering oil when I store it and have used the storage oil used for outboards to protect even further I always use cam guard
