As title suggests is it normal for smoke to come from the oil seperator? It's the 1st time I've run the car with the engine covers off so never noticed it before.
So does this mean it is not functioning properly? I'm getting a lot of black smoke and when I took the intake pipe off the turbo there was a bit of oil
Happened to me on my W124, engine oil found its way into the air filter box through the breather tube. The portion of the air filter positioned directly facing the breather tube was dripping wet with engine oil.
I think you can use a syringe of ceramic repair gel in the engine oil...it repairs worn piston rings. If it's marginal wear and tear like in my case.
Anyway that did the trick...air filter box has been dry since
