/\.... the "ball" valve you speak of is actually a PCV valve
its a ball that runs in a cone shaped race .. vacuum seal it off.. and WOT releases the vacuum and allows it to flow
( usually from air-cleaner, through sump space, to PCV valve and then engine )
if you have anything running to the base of the carb,, then one of these must be there else you have a permanent vac leak
if you wish to avoid a PCV system ,, and still have flow through ventilation
then it involves a one way valve,, and a rocker cover filter fitted to one nipple on the filler neck
( lowest nipple is the inlet , with a one way valve arranged so it draws through rocker filter towards the sump space )
and the highest point fed to the carb side of the air cleaner
( highest outlet to engine aircleaner )
if you totally want to eliminate the mustard under the cap,, then you block one nipple .. and provide a larger one directly into the cap, and run this to the aircleaner
( or PCV )
if you have a turbo engine,, and run lots of boost .. then you want to play close attention to this final method
( larger lines,, , a rocker cover filtered, free air source ..and a vent going towards engine aircleaner from top of the lid )
not one dot of mustard in mine ,, and i run turbo and LPG
( notorious for dew point on cold startups )

I have a turbo engine. I routed two lines, 1st from the center iron 2nd from the oil filler neck.
What am I doing wrong. I have more lung mustard then I have ever seen before, like my entire dipstick is covered to to bottom in the stuff

The way I understand it, fresh air enters the center iron, then leaves through the oil fill tube. This carries all the moisture out with it.
If you think about what is actually happening, the oil filler tube is thin sheet metal. It cools down faster than the iron in the engine. Heated air rises. When it encounters a cold surface, such as the inside of the oil filler "neck", it condenses water and drips back down into the pan. An easy way to stop this on a turbo is to drill a hole through the cap and let nature take its course, as others have said.
