PCV delete ideas/vent with catch can
I'm certainly not a fan of "breathers only." For one thing, millions and millions of on the road vehicles have been running PCV now for what, since 62 or 3?
I'm old enough to remember "road draft tubes" and how some of "our stuff" leaked big time FROM that road draft tube. But you NEEDED a road draft to help build a draft through the engine, and on many of those sloppy old girls, they STILL puked oil out the top breather.
BUT I've known some guys with newer engines (no road draft) who ran "breathers only." Guess what? The cab stunk. It smelled. Like OIL. That's because SOME oil mist was coming right out those breathers and back on the firewall.
I say fix the engine, and keep the PCV. In the meantime, you MAY well need to engineer some sort of auxiliary catch/ drain/ breather can to help the PCV along.
