Small Front Passenger Oil Leak (Pics Included)

Hey guys,

I just got done changing out my lift pump which failed at 136K and noticed a small oil leak at the front end passenger side of my engine. Here are two pictures with slightly different viewpoints :





I've read that a leak like this could be anything from a water pump to an A/C compressor. Before I start tearing into the beast I wanted to get some second opinions.

Any thoughts on what might be causing this? I just washed my engine so if I can pinpoint it more precisely I'll get some more pics in.

Thank you in advance!

Rob
