2005 G35x leaking tan fluid???

[Kennygs]

This is my first post so please forgive if I post in the wrong place or offend. My son has the faithful ole 2005 G35x half way across country at college and recently sent me a pic of leaking thick/greasy looking tan fluid collecting on top of exhaust pipe inside front passenger wheel. He says all major fluid levels look good and can't tell where it's coming from. Difficult for me to tell without being there. Hoping someone might have a history with this-any ideas welcome. Thanks (FYI I can't figure out how to post the pic-maybe not available option for rookies or this forum?)

Could be the valve cover gasket if the leak is from above the headers. Pull the plug wires and see if there is oil in any of the holes. This should be an easy fix.
