    I have brought this up in the forums before and I believe this to be the best oil catch can setup you can do.

    I used the best locations I could for this type of setup and the OCC I had.

    For the PCV catch can, I was inspired by a post from @sLick415 which gave the best location for a stealth setup for Cali smogs.

    Ther are a few others on here who have adapted this location and they are the following.

    For the CCV I was doing research online and came across two images that show a catch can on the breather hose.

    This a vacuum on WOT which the prius is usually high rpms and I have a bored TB.

    So I have done a setup with both.

    I know @danlatu had some ideas with messing around with putting another PCV on the valve cover or relocating it to the breather hose.

    I managed to do this without removing the intake manifold and in the near future will be updating the intake manifold to the latest version.
