Oil Bath Air Cleaner

running the "oil bath" dry could cause it to clog up, the oil circulating in the filter cleans the mesh, cleaning the oil bath means cleaning all the grunge out of the oil sump, and filling the oil to the proper level

The oil circulates in an oil bath filter??? What are you smoking Kurt?

Whatever I smoke(If I was to smoke) doesn't interfere with fact, i have watched a cutaway filter with a window in it in operation, to back it up i googled it and found a research paper ---look at page 6, and 10

if you want to prove it wash the element dry, just fill the oil to the proper level and go for a drive ----I have done this too, the filtering mesh gets oiled, the design is such that excess oil drains back, carring dirt with it

Does the mash in a oil type filter have to be cleaned with gasoline or some other type solvent on some type of schedule?

I was always told to soak them in kerosene and it seems to work rather well. I service a car that claimed to have vaporlock issues but turns out his oil bath filter was so clogged that it was causing the engine to run rich. As soon as he shut off the car it would be flooded and take a bit to get it to start again if hot.

Interesting paper, just wonder if this 1956 study had the present day dry elements to compare to, which would be more efficient?

It has to "circulate" as when the engine is stopped the oil in the cup is higher than the intake pipe. The only way for the air to get to the engine is to go thru the oil and pull it along with it , as the oil gets trapped on the mesh it fall back in the cup. It doesn't seem right but that's how it works.
