You can replace the oil filler cap until the cows come home. Until you fix that chip on the oil filler neck on the valve cover it will continue to leak. I had this happen on my 2011 M3. Took the car to the dealer for its oil change, after that I started getting seepage. Took it back to the dealer they replaced the oil filler cap, still leaked. I changed out to a new valve cover and the leak was gone.
