M54 Engine Oil Leak

Guys, I have M54 engine in my E60 and it has a leak which is very annoying since I am loosing 500ml about every 2-3 weeks. Here are some pictures of where I can see the oil.

1. First - There is oil getting accumulated in a puddle around the 1st and 2nd spark plug start from driver side.
2. Second - There few drops of oil between wiping it clean around 4pm and 12pm next day morning. The picture is of the bottom front left corner straight under the vanos areas.
3. Third - there is slight leak under the cover of vanos, but also the two electrical connector on the left of vanos appear to be leaking oil. Can this oil leak slip down to the second pic.

Which part is leaking that I need to fix is what I need to know considering the pictures. Is it the cylinder head gasket that is gone? Or something else.

Any suggestions are welcome.
