Now that depends on where in the world you are.
My UK spec '71 has a cylindrical oil seperator on the timing gear cover
(front cover?) and then a simple pipe going to a "Y" shaped connector
feeding direct to the carb inlets. No fancy valves, but then UK spridgets
didn't add all the extra gismos that went onto the fancy North American
exports ( three wipers indeed !!!)
