Oil on exhaust header causing it to smoke?

[xnj ranger]

So today I was sitting my truck waiting for someone, and I look and see that there smoke coming out of the hood. I opened it up and it looks like its got an oil leak onto the driver's side manifold thats causing it to smoke up. Any suggestions on what to do?
