Default Which pcv lines to cap?

I'm deleting my pcv by running dual breathers on my valve covers but can someone show me a picture of which lines or fittings need to be capped off to complete the pcv delete? Much appreciated

If your goal is to make less power and increase your oil consumption, this is an excellent way to go.

Deleting your PCV System is STUPID!

Couldn't have put it better, if your wanting to control your oil consumption get a good catch can. Breathers aren't really necessary unless your boosted or running a hefty size shot.

I put a cap on all the vacuum line and a breather on both valve covers and valley cover car runs great no problems no oil consumption. I did have it tuned like that though

IMHO it makes no sense to get rid of a properly designed PCV system.
