oil sitting on gear box

[Scott_]

Hi all , i have a 1981 2.8i capri, 4 speed . There's oil sitting on the bottom of my gear box , only a small amount and it drips after driving It. Its really clean golden oil , so i started wondering if it was the gearbox or actually the rocker cover . I'll attach a picture of the rocker cover . From the picture does it look like the rocker cover is leaking and is it likely that its running down and sitting on the bottom of the gearbox . 

Thank you all 

Scott
