Oil leak at front of engine! Help!

I have a Oil leak on my 2000 528i. Just to the right of the cylinder head (from the front perspective). It's coming from a black tube that goes into the side of the cylinder head (see pictures).

There are several possibilities in that specific area:
- I like Burning2 suggestion. It is the intake cam sensor that is located there.
- It also looks to me like the vanos oil line is weeping (very common) that is the black hose with pressure fittings of about 18 inches in length that is bolted to the vanos on top and the oil filter housing on bottom. Aftermarket vanos lines are cheap. Be sure to replace all 4 crush washers when you replace it.

If you want to find out for sure. clean the area with brake cleaner and watch it.

Also your CCV pipe (plastic pipe going into valve cover) looks a little tired - time to replace whole CCV system?

Okay thank you! Do you know if there are kits I can buy that are just replacement gaskets for the cam sensor? Or do I have to buy a new one?

With the simplest of Google searches, you will find this.

Then write the part # down, CRP products are sold at the AutoZone near me at least, and they can order it for you.
I have gotten CRP o'rings from them when I needed and did not want to order it online or go to the dealership and pay 5 times what I needed to.

I just took a shot (based on the limited info you provided about you car) at RealOEM to look at/for that O-ring for the cam sensor and came up with this (part#6):

If it is correct for your particular motor, it's available from this vendor:
