I'm looking into catch cans these days and found the UPR DVCC seems pretty popular. I found it on Adam's site and there is an option to add a breather so there comes all the questions... (And the install video seems to do a PCV delete?)
I've beening googling and reading threads about PCV/catch can/breather but still haven't found resonable explainations. Excuse me for my shallow understandings and silly questions:
1. To my understanding, PCV is a check valve, which vent to intake when there is pressure in crankcase. So if the aim of PCV is to eliminate pressure in crankcase, why a breather is needed? Because a breather is also used to vent pressure to atmosphere.
2. If a breather is installed and let's assume there will be no pressure in crankcase anymore, then how can blow-by be pushed to catch can?
3. What's the benefits of deleting PCV? I'm assuming check valves will be needed on catch can hoses as a replacement for PCV, right?
Thanks for sharing your understanding :cheers: :cheers: :cheers:
