1995 U320 M11 Oil Leak

Our 1995 U320 has an oil leak and so far I've been unable to identify the source. It's on the engine perhaps between the oil filter and the alternator. It appears as if it's coming from the oil cooler. Does anyone with an M11 or ISM engine have experience with a leak such as this

ANY Oil in the coolant tank?  If so, you may need to determine to condition of your oil cooler.  A radiator shop can fix the cooler unless you decide to replace the old one. They have been known to go south.  pc
