Hey guys I am trying to get this fixed as soon as possible... I have a oil leak and I have replaced the oil filter and O-Ring Twice and Just finished replacing the Oil Filter Housing Adapter Gasket. Neither were the problem. Cleaned the areas right after each replacement to make sure. The Oil Leak is coming from a plug/bolt/screw on the back of the engine block to the right of the Oil Housing Adapter. I need that screw/plug/bolt part number or anything really to order that. I have a 03 Mini Cooper 1.4L base model. Area is circled in the picture attached.

 

I believe that may be screw plug HERE, #3 below. Let me know if that looks about right. Be sure to make sure that the threads on the block itself aren't stripped.
