oil leak
 

I have a '95 E320 wagon. I noticed several oil drops on the driveway. I checked the engine and noticed the oil was coming from the driver's side front on the very bottom side of the engine.
It is difficult to see, but looks like a cable running to some sort of round device attached to the engine. Based on my description, does anyone know what that is? And is it simple to replace?


Thank you

Phillip
