PCV hose collapsed
Some times if your puttin around in traffic the fuel will load up and if you throttle it , it can put out black rich smoke that can be mistaken for oil .
But at the same time , ive seen oil puddle up in the intake from the pcv system and sudden acceleration can send that oil into the intake runners .
Watch your catch can and see how much oil it has in it .
If your geting a lot of oil in the can in a short period of time you may have other issues going on .
