i have both cam covers running into a catch can of 1.5L capacity, the return pipe to both the turbo intake and the intake plenum have been blocked off.
i manage to fill the cartch can at a drift prac or comp event, with about 1 l of oil from a whole days thrashing on the limiter.. is this normal or do i have excessive blowby.
I am well aware that RB series engines produce a lot of oil movement in the head at high rpm, some of which will find its way through the breathers.. so is mine normal or excessive?
