    Blowby Catch-Can Plumbing ?


    info appreciated - anecdotes and 'putta V8 innit' please refrain ...


    always with forced induction but also with HiPo engines crankcase evacuation or other means than PCV is needed for peak cylinder pressures.



    * need to install 'catch-can' on 250 Maverick - typical catch can uses side entry large filter vent on top. no room at typical top of VC PCV/Vent locations for catch can and filter vent - no clearance anywhere else under hood...

    currently runs two open vents on VC and large tube/vent from crankcase's mechanical fuel pump block-off plate. ignition side is busy and exhaust side heat limited.




    ** ? FOR CLEARANCE - CAN CATCH CAN BE LOWER THAN VC TOP PORT WITH CONNECTING HOSES DOWN TO CAN ?



    sorry for caps ...



    FP boss vent and SC return to Oil Pan ignition side

    VC - CK vents Maverick hood is lowest and 250 is tallest small block six....

    open location by heater motor would have filter of can lower than VC ports.

    Run the vent hose from the front grommet location that you currently have a filter on to the can. The can should have a provision for the filter. If not run a hose out of the can and put the filter on it.

    Catch Can Plumbing redux ..

    3/4" tube to first can gets crankcase vent from FP blockoff, second gets VC gases, tested to @ 8-10 lbs boost so far
