Redoing oil filter housing gasket and replace the entire housing with a 15K miles used one from F30. I had this gasket replaced by dealer 3 times and it recently leaked again!!!!! This time I will do the job my self, the mating surface between oil filter housing and cylinder head had residual gasket material on. I bet dealer probably never clean the surface and just slap on a new gasket which is causing it to leak 3 times in a year.
Here is the old housing
