Hi All! For the last 2-3 years we have had an oil leak somewhere under the hood that drops into the botton plastic protector, even through the sway bar. This leaking only happens when a reasonable number of kilometers are driven. Not when 5-10km. We firstly replaced the top gasket in the motor and the top part of the motor is dry since then. However, oil kept dripping. So we replaced the oil filte housing o-ring. Later it was the time for a bolt in the back side of the motor that seems useless (kinda as to cover a casting hole or similar), and the backside of the motor never was humid again. Since the oil pan was really wet, the next to be replaced (in last Christmas indeed) was the related gasket. But we kept having oil in the lowest corner of the oil pan to motor connection edge. So we added some silicone to that corner to grant (or try to grant) this would not leak. But the oil dripping persists... and such an oilpan-motor edge is still wet over the silicone. A couple of days ago we cleaned the best we could with brake cleaner to try to identify any fresh oil coming out, but it is not possible to remove all the dirt without disassembling many parts. The vanos lower area seems to be dry (still dirty though). So we wonder if the problem could still be the oil pan gasket, or maybe the cylinder head gasket? I tried to provide some pictures in case these help, but cannot find how to load them from the PC... I am sorry for this. Any suggestion on how to identify the origin of the leak? Where this may come from? Thanks a lot! Kate
Hello, to load pictures there are different ways - Load the picture on a sharing site (i.e. imgBB, postimages, etc) and place the link in your post - Click on the little icon above the box (where you write the post) About the oil leak: did you check the gearbox?
Hello. Thanks for your message. I tried looking for the icon to attach/load pictures directly, but only have acces to add links/URLs, which I do not work with. I have just noticed that the option to load from PC is underneeth the text box, right to the "send" button. So I have just loaded them. As for the gearbox, the oil replacement has been done and it is perfectly dry. The leak comes from somewhere in the mid-front of the motor... Any suggestions?
