    downdraft tube/ crankcase vent. Whats the plan here?

    Wondering what people are doing for this issue? I dont want to use a catch can. Currently have a down draft pipe but wondering if any one has had success with cycling this back into the intake track or possibly running into the exhaust? I was thinking of putting a fitting between the air filter and turbo for it or maybe a fitting into the exhaust past the downtube?
    Thoughts?

    Im more interested to see if anyone did the exhaust route. Running it back to the intake seems messy and asking for issues.

      I'm pretty sure mot people just run a long rubber hose down below the engine with a filter on it if they aren't using a catch can. What is your reasoning behind not wanting to use a catch can?

        I just ran a tube down near the control arm with no filter :)
