Had my car serviced in june and since then oil has been leaking on a daily basis from where the oil filter sits. Had it bacl to dealer 3 times now and they still cant stop oil from coming out. I think htey might just be removing the cap cleaning it and putting it back on instead of putting a new seal on. Has anyone else got this problem? Car was fine up until first service and its just started doing it since dealer got hands on it.
