Bypassing the blowby gas system to a catch can?

[John Larson]

Will asked:  "Would removing the blow by from the intake cause running
problems? My
concern is whether the mixture ratio be altered since it'll be only fresh
air passing through the intake."
What are you gonna do about the big vacuum leak you create when you open the
crankcase vent to the air?  If the car stumbles or even dies with the oil
cap off, it's REALLY gonna be bad with a perpetual 1" hole in the case.
