Reply to "To PCV or Not to PCV??"

I've noticed the guys with the big horsepower engines keep the PCV function, without recycling the vapors into the carb, by putting a little filter on the valve cover where the PCV valve was. So, extrapolating from GP's information, the crankcase would still get fresh air replacing the vapors, so keeping engine life higher, but not introducing the vapors into superchargers.

Must be that rattling little valve acts as a check valve. This would prevents the sucking of combustible air/fuel mixture back into the valve covers, when there's negative pressure in there, like maybe when starting the engine.

The filter on top of the bad-a.. motors just keeps the engine compartment cleaner, but they leak a little, like when the engine is started and sort of smell bad. I'm keeping my PCV check valve inline to the air cleaner, based on GP's explanation and the smell and vapr factor of the little filters. Some valve covers just come with the little filters, like my buddy's '69 Charger's Edelbrock valve covers came with chrome rectangular filters. I've also seen the PCV valves on just one valve cover. Wonder if it's better to have a PCV valve on each valve cover, like for better crankcase breathing and maybe better engine life. Though experience has taught me engine life is tied most closely to how often the oil is changed and how hard the engine is run. Some teenagers rev their motors lots and to the rev limiter, while cutting costs on the oil changes and their exhaust pipes expell smoke, expensive to repair, rice-rocket, import engine smoke. Lessons to learn for some.... Why do I digress so much??? Which reminds me of another story....
