Default PCV Delete

Ok so I plan on doing this and following most of what this guy did....
https://ls1tech.com/forums/showthrea...ghlight=%21pcv

What should I use to plug the top of the throttle body? Will just putting a filter on the oil neck be enough? Where are all the places I should block off? New to LS1's so please help!

Cap off the valve covers and put a breather in the oil cap. Or you can buy the Metco breather from Thunder racing. You can buy vaccum caps at any auto parts store.

Advantage is no more oil being sucked into the intake from the crankcase. This keeps the inside of the intake cleaner and reduces oil consumption (slightly). It's also done b/c some people like how it looks as you get rid of some of the tubing and the PCV itself.

where you got circled is not the PCV its the EVAP connection to the EVAP cannister, the PCV is on the passenger side clipped down on the valve cover, runs to the intake manifold, then in the back connects on the back of the passenger side valve cover and splits into a Y shape, then runs to the drivers side valve cover.
