I toyed with re-routing the exit of my oil catch can back into my pre-throttle body charge pipe. In my research, I found many varying opinions, some suggesting that I should completely cap off/eliminate the PCV system. I am now running well, with reasonable fuel trims, so I don't plan on messing with my current configuration.

Do you have any additional info and pics of your setup?

its stock right now (k&n drop in) I added the catch can about a month ago just because I think its a good idea to keep the engine cleaner. havent noticed any difference but I dont even know what id be looking for or "feeling" for by how it drives or uses gas . I usually put the mid octane fuel in but maybe I should be running the highest octane ? yes its not a Yaris ahhh sorry
