Default Catch can route


In LSA setup, how is this routing? Connected valve cover to valve cover. Valley cover to catch can. Cleanside oil separator at oil cap.

That looks like it would work okay.

in that type of set up, blow-by will push crankcase vapors back into the intake (via the green line) where it can "soil" the combustion process


i prefer a two can set up, or simply a filter/breather (in place of the green line)

I do have two cans set up. In the green line, I have oil separator sort of catch can in place of oil cap. Elite Engineering calls this oil separator. It catches oil and oil goes back to heads.

I have this t line set up for dirty side picture above currently and I still got oils in my supercharger lid and intake, so I was thinking different route which I posted in my original post.

right. the issue is that green line. it's either pulling oil when theres a depression on the intake side, or pushing blow by gasses through when there is positive crankcase pressure.
