oil leaking from breather

You guys are on it. PCV in one cover. breather in the other. Air in the breather on one side, out through the pcv to the carb on the other. Make sure there are baffles in the covers under the breather and PCV to keep the oil from splashing up into the two. If that doesn't tke care of the issue you may have bigger problems like too much blow-by. Cross that bridge when you come to it.
