The duckbill nozzle or nipple (designed to keep water out) attaches to the bottom of a small plastic, tube-shaped chamber which has a line to the bottom of the air box. If you're finding oil dripping from the nozzle, this means there is oil in the bottom of the air box. Pull the air filter cover and look under the filter element. Oil in the bottom of the air box is symptomatic of over filling the oil tank. The oil level should be halfway up the dipstick with the engine/oil at operating temperature - check while the engine is running and with the car on level ground.
