I've been looking around on where an oil leak is coming from on my 2011 Mini Cooper and would love some confirmation. I'm think it's coming from the vacuum pump o-ring; I have a pool of oil to the right of it (green square - I cleaned up most of it). Any ideas if this is correct? Thanks for your time.

 

Yep that looks like it. When its the oil filter housing its lower under the front of the MINI>

Looks like you have an N16 MINI engine?
