Says some guy on the internet.
That said the new PCV systems are getting better at drawing out oil vapor. When I was looking at Challengers around '12-'13 catch cans were all the rage on the R/T's because the intakes were filling with sludge from the PCV.
My brother put a programmer on his '11 Coyote and it had problems with the PCV vapor (because of the piston cooling jets) and he had to get a catch can for it.
Might not be bad thing to do no matter what engine you get anymore.
And then there is my old pullout '87 5.0 that has a bone dry intake although it should have more stuff floating around in the crankcase than all of the other three combined x3. A generic PCV in a Ford Racing valve cover must not be that efficient compared to newer PCV systems.
EDIT: Talked to my brother, he thinks it is more of a urban thing. He knows it is a thing but out here in the sticks where everyone runs quite a bit of highway it isn't a big problem.
