- Back to my oil leak, I have a theory, it is likely RMS b/c according to the photo below (courtesy of youtube 50sKid video), if there is a RMS leak, oil will trickle from #1 (RMS), down to #2, then along that long bolt and you will see it at the bottom of the bolt (RED arrows).

- Alternatively, it could leak from ONLY the rear part of the oil pan gasket #2, but why only the rear part of the oil pan gasket?

- I understand that it is not environmentally friendly to have an oil leak, but since this job is sooo big, I'd rather leave it alone and add 1 qt of oil every 2K-3K.

- On a different topic, I did a CCV Mod (a la BavarianE39), which reduced my internal oil consumption (piston ring issue) from 1qt/300 miles down to zero consumption. Interestingly, this mod increases crankcase vacuum and supposedly air is sucked in from outside ---> the RMS ---> into the engine, which may reduce RMS oil leak (if it is truly RMS leak). You can see my CCV Mod in thread #164 below.
I drove the 2004 X3 2.5i for 700 highway miles, there were a few drops of oil seen at that long bolt, but oil dipstick stayed FULL for 700 miles.
