I noticed an oil leak in the megane. It's leaking down to the engine mount (the gearbox one under the car). Picture shows a bit of wet oil from the engine bay. Under hard acceleration and high revs, I think the oil is spilling out somewhere. Can you guys give me some guidance on where to start looking? Or any common places where leaks occur?

Car in question is a 2004 Megane 1.5 dci with 133k on the clock.
