I have read and read and read some more but there are so many different options. What is the best and easiest way to modify the PCV system for my on3 set up? If i delete it and do a catch can system with a breather, doesn't that create unmetered air going into the intake??

i run a catch can. Cap off the nipple on the throttle body and the nipple on the oil fill on valve cover, If you have stock valve covers.

if you have a very poorly matched cam the produces zero vacuum, then it would create an issue. Other than that, cap the tb pipe and run some lines from the valve covers to a breather tank
