Rocker cover oil leak

Hi had new 150 for about 6 months now and have had a leak around the gasket on the rocker cover . Have already had it back twice to the dealership and both times change the gasket , but still hasn't fixed the issue so there must be another problem what might causes this leak apart from the dealership telling it must be the gasket ..

thanks

Had issues with the rocker cover gasket after the 40k service as I requested they check the valve clearance instead of just listening to them. The leak finished up being on the very back of the rocker cover and over 3 attempts to fix, the leak managed to soak the sound proofing on the firewall and took ages for the oil to run out.
