Help wanted. Is something suppose to be where the 2 red arrows are??? It is a Peugeot 307 CC with the 103KW engine. This is on the end of the head at the flywheel end of the engine? I am really stressed out that maybe something is missing. I am presently trying to locate engine leak, and wonder is this into the coolant chamber of the head or the oil chamber. What is suppose to be attached to the 2 points? Please help me if you know? I cant find anything on it in the workshop manual, and tried googling it with no luck. There are 4 photos loaded here for you to see. Thanks.
