340 motor pumping excess oil on right side

can you clarify rocker shaft on wrong ,its only on the right side , not sure about the push rods , thnx
ok pulled off the valve cover I assume this looks correct , but I am concerned about oil deposits on intake as a result running an open mesh filter with no tube to carb , rings ? only on the right side though ? maybe just change covers with more baffling to restrict the oil from flooding the breather tube to carb base
