When the engine is running, oil is tossed off the rocker arm and onto the exhaust side of the valve covers and then it puddles in the breathers. If you remove the breathers and cover the breather hole in the valve covers with a plate, the fumes and oil will not have any path to escape. Problem solved.
Total agreement!!!!
