It does not matter what side you run the PCV on. The information relative to the Baffle is 100% correct and will fix 90% of the
oil draw through the carb.
I should mention that the crankcase must be vented for the PCV system to work properly. If you are venting to the air cleaner or "breather" you will need to baffle the vent port as well.
If there are no provisions for a baffle, you can fashion with SS sheet metal and a few small hand tools. Remember, the baffle is used to stop
oil from splashing in the port. Therefore, it should allow any
oil to drain back into the valve cover and down into the engine. You can drill a hole on each side of the port and pass a long screw on each side to secure the baffle over the hole. I used chromed acorn nuts to finish the installation.
Make absolutely sure you use locktite or some form of retension to make sure the screws and baffle do NOT come loose.
Hope this helps.
