I've just purchased a 2.2 GSI with a Z22SE engine. About two weeks ago I saw some oil drops below the gear and lately the oil level of the engine has been decreased. I looked below the car an saw that all the gear area is pretty oily.
Next, I searched for the upper part that looks oily, and found a part that I don't know what it is, between the battery and the left headlight. I think that this part is the cause for the leak.
I attached some pictures. Please help me to identify this part.
The car is an 2002 Vaxuall Astra GSI with Z22SE engine and an automatic trans.
