catch can

  1. Engine and Technical Discussion
    I'm attempting to install a universal catch can for PCV. I'm trying to find out which hoses and connectors I need. It looks like the valve cover out barb is 3/8 inch and the intake in barb is 1/2 inch. Does the factory hose just have one end 3/8 and one 1/2 inch? So can I just use 3/8 inch...
