Don't know about your car design, but happens to me as there is one pipe (in built metal) made on the upper cover of air filter box, which after tightening closes it's head in pipe from engine, usually it's on that side.

There is PCV valve that has some air/cng releasing back to air filter box and comes with oil too.

any further explanation...
