2003 Mercedes CL600 Oil Leak Information

I have a 2003 CL600 with the Renntech ECU upgrade and now putting out 625 HP and 745

Lbs. torque close to the CL65. Love this car but so scary to own as last year I took it to a recommended mechanic to fix the electric cooling fan not working. $4,000 later and the electric fan, radiator replaced. Only 55 k miles but the car is approaching 19 years old. Recently I started seeing some small drops of oil on the road/driveway but now its coming out much more and even in a small stream if I park in the driveway and then restart to move into the garage. Without lifting the car yet it looks to be coming from the passenger side front just behind the front bumper assembly or passenger side front of the engine. Does anyone have any Idea what this could be? Is there separate engine oil cooler and where is it located? Any help would be greatly appreciated. Love this car.
