Great I'll check that article. Thank you.I think that is an autocorrect mistake, what I think he is saying it to get rid of the PCV valve altogether. Proper PCV is good for environment but also for you engine. Some reading on PCV (promo article for their adjustable on but anyways) article
You can always have an oil separator/catch can in the PCV circuit, which is nice have for anyone with a PCV circuit.
Btw what is with the IronSwede nickname? Myself I was born and raised in Stockholm. 🇸🇪
And Ive had the username 'Ironswede' 30 years. Even owned the domain for awhile. No one has ever asked me.
Im born and raised in America. But Ive been into Volvos my whole life. Owned tons of them. My thought back in the day was the Volvo logo is the symbol for Iron...and they are Swedish so it just worked. Even had a pen pal over there for years. Before email was a thing. My dream car was always a Nova. Once I got it I kinda got away from Volvos. Would be nice to have a daily driver though one day.
