oil leaking..smoke comes up...???

alright, well on my integra whenever my engine gets warmed up and i rev it a little bit...I see smoke coming up under the hood, so I open up my hood to see where its coming from, I look to the left of the headers and I see all the smoke coming from there, it looks like a dried up oil around that area starts to smoke when the engine heats up...I changed my valve cover gasket and its like my engine still leaks oil...anyone know where else oil leaks from around there???...please help...
