oil catch can

what size is the crank case hose when I decide to install a catch can?

IIRC it's 3/4"

Yeah, 3/4" Inside Diameter. Don't use standard Heater Hose. Oil vapors will degrade it from the inside out and cause it to be a pourace mess. I know this from experience. Suggest using low pressure power steering hose.
