OK, take a look at the first pic (696) it shows the wiring loom below the vacuum pump that connects to the oil pressure switch. Oil will seep out of this from the oil pressure switch when it goes bad. It makes it very difficult to determine exactly where the leak is coming from. The other two pictures will give you a pretty good idea where the oil pressure switch is located. It's right under the vacuum pump. Like I said earlier I would replace this switch first then the vacuum pump.

As for your pic...I think if you just had an oil change that may just be oil that spilled from the oil change. The leaks I had where from the vacuum pump seal and the oil pressure switch.

Hope this helps!
