I believe drax is right. I’ll post an update when I do my oil change in a few weeks.my comment still stands bc OP said "I contacted a parts department and even for the metal one it gives them the rubber o ring even for the metal pan. The metal and plastic pans are calling for the same rubber o ring which doesn’t sound right to me "
you say different o rings. gm says same one.
