| A new member/o2 Sensor Hello Everybody. I don't own a BMW but my son does; a 1997 740i. I've replaced the engine an am doing some other work on it. The engine overheated and blew the head gaskets thereby causing one head to crack. Does anyone know where I can get a picture or diagraham of the o2 sensors connected? I want to verify that the o2 sensors are connected properly. |
