Yes, because the reason the PCV exists is blowby. Even an NA fuel injected (not DI) engine will have blowby. Combustion gases, H2O, unburned fuel... all will get into the crankcase and therefore into the intake via the PCV. But my car has 275k miles, so I gotta assume more blowby than in 1998. If I catch that in the can, my intake air is cleaner. Better for the engine. Better for anything that breathes air, too. No?
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
