Custom Crankcase breathers question
Hey guys, I would like to remove the stock PCV system and install a crankcase breather.
What do you guys think about this alternative to the PCV system in the 5.4L Super duties?
Has anyone done a write up about this that would not mind posting?
Thanks!

Why are you going to vent all that stuff into the air, and then breath it when it comes into the cab? 
Also, if you leave the PCV system active, and just vent the other side, the PCM will get "unmetered air" that is not passing through the MAF and will cause a lean condition.
I'd leave it alone if it's not causing any problems. It's not going to help performance at all.
