Hi, everybody, it’s about my Insignia 2.0CDTI. I recently made an oil change including all filters… and that’s how it went off… a few weeks after the oil change my car swarmed up and told me to check the oil level because it was too low. And now I also knew that the oil stains in the parking lot aren’t from my neighbor but from me… My first suspicion about the oil drain screw because I saw oil pots down there… so I’ve got the The new one from the accessories used the old one again. (I always did this with the Vectra CDTI and kept the same screw tight for years). But a few days/weeks after that I now have oil stains under the car again… As it looks from above, it pops out somewhere in the back right (passenger side) … so where the oil filter is also… Now I remembered in retrospect that I still wondered that the new oil filter so loosely in the back The oil filter was out of the accessory… can it be that this is responsible for leaking? Or is it if it is more due to the rubber ring which seals the oil filter housing? Basically, it has to be on the screw or just the oil filter housing because nothing else was open where oil could come out… and before the oil change everything was dry with me… What do you think about it?
