      a catch can filters stuff out, collects it, and allows the oem system to keep working to a point. this system would require a new oil pan or tapping this one (not smart), and returning goop to the pan... or dried goop to the intake valves!

      either way, its not a good idea, at least not from what ive seen people do with them on other platforms.
      It sounds like you aren't very confident about this fuel dilution theory. Fuel is much lighter than oil, would likely stay suspended in the air and be vented, no problem in that. Remember the Crawford AOS stays heated, so anything that is a vapor would stay a vapor it wouldn't condense.
      Also it would return oil to the pan. If you're oil is dirty you're oil is dirty it doesn't add anything extra to the pan just what was in the oil in the first place.

      To the interested parties I got an email from Crawford asking me about how much interest I have garnered. They also would like to look at a car for a little R&D and would like to know if there is someone in the San Diego area would be willing to do so.

      just look up fuel dilution... the fuel will re-condense during its travels... its not going to just burn off... if it did, the stock system and catch cans would be amazing. they aren't. never will be.
