I don't know what caused this. It's hard to see exactly where it's coming from. It appears to be from a round indent on the back of the engine. I just replaced the water pump....
What are we looking at here besides some unknown engine in some unknown vehicle (I assume). All I see (clearly) is a distributor rotor cap, valve cover, throttle linkage & spark plug wire which evidently(?) appears located on the driver's side? Is this an Oldsmobile?
EDIT: I missed the dual-reservoir MC. How about a little more information regarding the vehicle.

I am guessing you have a 394 Olds from the piece of valve cover that is visible. That "round indent" is likely a frost plug leaking. You'll need to get a mirror to look closer. If it is a leaking frost plug, you'll need to replace it, and most likely others.
