Lay up in humid conditions
Put simply, it is a unit that draws in ambient air through a silica gel pouch and introduces the dry air into the engine crankcase via the oil filler tube. On it's way out, the air is able to pick up condensation/water within the engine and effectively remove the water that causes the rust.
My question is this :-
If I were to make such a unit for the Rotax 912UL, where could I introduce the air into the engine so that it circulates within. Any thoughts ??
The two cone air filters have home made silica gel bags encased around them during longer periods of lay up.
Thank you sir for your kind attention.
Sincerely.
