The crankcase vent is the black elbow (just behind the oil fill cap), and associated plumbing that goes to the top of the air cleaner.....there is no PCV (rattle) valve that I am aware of.......
The air cleaner is under a slight vacuum, so vapors from the crancase (under slight pressure) flow into the air cleaner......and inside of the air cleaner housing, they are discharged into a "sort of" vapor condenser......and the oil vapor that is entrained with the air exiting the valve cover.....is somewhat removed, and drains back into the oil pan......
