One thing I keep wondering about - and I will read more of that article - is why the route back to the air intake?
To provide more of a "draw" to better evacuate the noxious stuff in the crankcase?
It seems that the PCV system in general does two things:
1 - Improves upon the evacuation of said gasses and yuck
2 - Does it in a way as to be "eco friendly"; i.e. running the trash back through your engine.
I live in an emissions free zone, and have no intention of ever having my car "inspected" for emissions.
And I ain't particularly eco-friendly either, but I don't litter if that makes it better.
So that said, I'd be more interested in methods where a good evacuation of the gasses occurs, but without running whatever junk back through the motor / or intake.
The minute my brain goes there though - I see the dreaded BLM numbers go high in my minds eye.
So I guess what I will have to do is look at what the racers / off road only guys do.
Help me out.
