I noticed a slow oil leak on my E350 a few months back. I don't drive it just a whole lot so I ignored it, then forgot about it. I took it to DC and back in July, then noticed that the oil leak has sped up a fair bit. I parked it and didn't drive it for a couple of weeks. Got off early today so I started poking around to see if I could find the problem. Looks like some sort of sensor or some such on the back of the head behind the cam on the left side of the car is where the leak is at.

I'm pointing at the thing in question here:

You can see it's a bit wet/sticky looking around the general area, and there's actually a drop of oil about to fall if you look in the mirror.

I'm guessing there's a gasket or seal or some such that needs replacing. Anyone offer any advice on what parts to buy and how exactly to get to that thing to take it loose?
