I have a 1999 S80 T6w 126, 000 miles

I bought this car a couple of months ago from GA and had it shipped to WV. Everything was working great until yesterday (2-25-12) I noticed oil on my driveway, not a little a lot of oil. I took it up to a oil changing place where I had the oil just recently changed with (Mobil 1 synthetic high mileage)where upon they put it on a rack. Upon inspection there was oil dripping from the pan coming off of what appears to be a tube underneath the turbo. Well looking at it from the top side of the engine I can see that it looks like there is oil coming from the bottom of the Cam sensor dripping down to the shield and tube underneath the cam sensor.

Upon investigating in the Haynes book I show that there is a cam plug behind the cam sensor. Could this be what is causing the leak? I don't feel it is leaking from any of the turbo seals, nor do I feel it is leaking from the head. I checked the oil dip stick and I do not see any milky substance in the oil (which is good) so no blown head.

The car seems to be running great with the exception of the oil leak. I need to get an opinion on what this could be? If it isn't the plug what could be the other senerio. I have included pictures to describe what I am talking about... Some PLEASE HELP ME!

 

if you suspect it from the Cam shaft seal then pull the sensor w/ cap and see if you see oil. if so replace the rear cam seal. It should be obvious if there is oil as the seal will be blown out versus being recessed in the cam cover.

 

Not sure if the travel of oil is right, but it's not unusual for those oil return lines from the turbos to leak. Not a big fix... Just a pain-in-the-a$$
