I know its not the right place to talk about the above but my girlfriends 1.0 3 cyl job is leaking oil from a large pipe at the front of the engine? The pipe looks like it is just squeezed together but Im not sure how, I have tried clamping it to get a better connection but it's still leaking

Is this a common prob and how can I fix do I need a special tool?
Thanks
