Image Unavailable, Please Login Okay, so doing my first oil change on the F430 tonight. What the hell else am I going to do right? I bought the OCK (along with the tool) from Ricambi. See the attached pic. I know the white filter goes above the main drain plug where the plate with the 4small screws come out. The green o ring goes around that plate, and the open ended gasket goes below the filter. What the hell is the black o ring on the right for?? Watched a bunch of vids on YT and read a bunch of articles, but can’t find it for the life of me. Sent from my iPhone using FerrariChat.com mobile app
