If your oil pan is leaking on an N55 *RWD* you'll need the following:
-Oil pan gasket
-oil pan bolt set (one-time use, do not dare re-use these) + 2 bolts required that are not part of the set
WHILE YOU'RE IN THERE-
-Oil level sensor seal
- change oil
- turbo drain line
In addition to the above- If you have an *X-Drive*, you'll want to also do-
- differential/ output flange to oil pan seals
- diff output/ flange output seals
- axle nuts
- alignment (some suspension will have to be unbolted to remove the axles)
Keep in mind that this job requires access to an engine cradle to hold it in place, as the front subframe MUST be unbolted and lowered away from the engine to allow clearance for the oil pan to come out (the subframe can stay in place hanging from the suspension arms, but it must be unbolted from the engine- thus why you need a cradle to hold the engine (never trust a cherry picker/ engine hoist for this!!! you do NOT want to be under the engine if the hydraulic piston of the cherry picker gives out!)
