Dang Battery

I'm not sure if it is leaking, or it's just blowby from it being cold, Doesn't have that sweet smell of anti freeze. I need to find a set of twist lock breathers that have a hose nipple on them. I can find push in ones but not the twist in ones. Then hook the hoses to the check valves in the exhaust. There is no PCV system on the engine, just 2 breathers to atmosphere.
