Narrative:

All neo (new engine option) engines. When doing postflight walk-arounds or even preflight walk-arounds when the plane just pulled in; there is a lot of smoke and strong fumes around the neo engines. The smell and smoke is sometimes nearly overwhelming. This stays around for approximately 10-15 minutes after the engine has been running. Sometimes even longer. When doing the walk-around in the dark with a flashlight; the light beam shows all the smoke particles and it looks like heavy fog. Spoke to ground crew as well who notice the same fumes and smoke on neo engines. Told me it smells like burning oil. I am concerned about health implications from this. There is no way of avoiding the fumes and smoke.
