Default Smoke coming from under hood

As I was heading down the street from my house this afternoon I noticed some smoke rolling up from under the hood. It wasn't heavy, but enough to grab my attention. I pulled over and opened the hood. I ran my fingers along the valve cover and found a small amount of oil was dripping onto my headers at just about the middle of the engine (just a bit towards the front).

I checked my oil levels which seemed fine given that my engine was just running as well as my antifreeze to look for any traces of oil, which I didn't find. I also checked all my catch can lines and they were dry. Furthermore, by the time I got it back to the garage it seemed to stop smoking so I let it idle a bit more to confirm and nothing else smoked out. I'm going to re-check all of my joints in my catch can system, but aside from that does anyone else have any idea what could've caused that?

FYI, I have the Paxton w/ IC pullied down to the non-IC boost levels. I wasn't getting on it today or really in the last few weeks and I'm not getting any codes from the ECU. Thanks in advance.

Actually, I just checked again and it is continuing to do it. It seems like the oil is either leaking or pooling right around the center bolt on the valve cover. The next step would be to pull the valve cover, right?

Just had mine off. Not hard to do at all. They use a rubber gasket. Consider just checking the torque. It should be at 89 in-lb (not much). Do the normal center and rotate towards the outside technique.

If you need new gaskets, get them from Ford. Was actually cheaper than Felpro.. (hard to believe). If you have to do the passenger side, unplug the harness from the CPS and the A/C so you can pull it up and out of the way (life will be much simpler).
