Steve, not to dubt your experiances, but l think this has a lot of perspective.
Yes, its possible to DOW with clasical, minimal effort and cost sistems, but as long as l get soot in the intake manifold, possible tar on valves and rings, condense in gasline etc on my sistem, l am not pleased with those sistems. We live in 21. century after all!
Actualy, a hay filter is allso a scruber. Is there a problem with its condense disposal too?
I am not saying screw the old prooven sistems, l say make them better!
to be exact, this is what l have in mind right now
This is a scrubber haifilter, with recirculateing water via venturi ejector (carburator stile).
Self washing, and shuld work better thain a conventional hayfilter without many more complicated gadgets.
Of corse, my statements stand for water scrubbers. Antifreeze is a nother question.
