Interesting and a good point. It's definitely not unusual to see that milkiness in both the Ford EB, VW GDI PCV catch cans, yet I've never seen any evidence of it in the oil pan. My guess is that what little water condenses and returns to the pan just vaporizes again and eventually does make it out into the can/intake.Checked out the two you mentioned and now understand. Looks like Ford created a passive no-maintenance device to help limit crankcase vapors going to the intake and therefore maybe possibly limiting or slowing build up. Understand manufacturers not installing catch cans from factory due to expense and fact that most folks would not check drain maintain them...heck I bet a lot of folks don't lift the hood anymore. So this appears to be an answer for that.
My only limited experience with a DI engine is our current 2019 Subaru Forester. Not turbo, just DI. Put a catch can on shortly after driving it off the lot...maybe 500 miles on the odometer. Have about 6k now. Check the can about every 1.5k. Have gotten at most maybe 1/4 cup of condensate total in that time.
Based on the fact that a couple of times the condensate was milky or grayish colored I don't think I'd put a more baffled plate on the 2.3. In fact I venture to say I'd want no baffles! My reasoning is that baffles will condense vapors and drain them directly back into the crankcase. If what I've seen in my again very limited experience is some condensed water and/or fuel vapors I wouldn't want to be dumping that back into my crankcase. Would rather collect and condense 100% of the vapors in the can and get rid of it but again I see why Ford would create a baffled plate. I will be installing a CC with stock baffle plate.
