I see some of the bigger motors have these fitted how does this box work and does any one have one they dont need ? thanks seagull

Well according to god breather boxes are to separate the oil from the air/oil mist thats in your case and to let your case breathe by venting via lines to your carbs and to then return the oil to the case on deceleration,and i have no idea what i just said so direct all enquiries directly to GOD.

:jesus

They basically act as an air filter for your case / tappet covers and reduce crank case presure thus reducing blow by. I use a K & N filter on top of a funnel. This allow breathing when under pressure and when not it just runs back into the case.

You can buy breather boxes for like $50 which are alloy case filled with foam .

oops forgot to say I am not god, the above is just my opinion :party

a new or s/hand unit ( or I will swap for a fuel filter like the one I am sending you )

you can make your own. Got one welded up at an exhaust shop, bought the fittings I needed and then the hose out it all together. Box cost $30 to make up plus hose plus fittings

I have one of these in the shed, it is what Mike is talking about.

You have U2U :>

Oh the stuff in the pic is the kit BUT the Alloy Filler cap is not part of that, these are sold on their own.

I thought the blowby box was designed to fill engine bay & cabin with a fine blue haze & asphixiating fumes:jesus oh well, back to the drawing board
