Hello, my Zafira B regularly forms an oil film at the oil tank, and on the left if you stand in front of the engine. it has to come somehow from above, because in the area marked on the photo it is also oily. Can the seal be leaking to the water pump? Or where else can the oil come from? Would you like to start no suspicious repairs, but first know where the oil comes from. Does anyone have any idea how to find out? Greetings Axelino
