I'm a bit concerned by how much engine oil there is in the air pipes on my 1998 c250td
There's quite a bit of oil in all of the air pipes from after the air filter all the way 'round to the intake manifold so I assume it's coming from the engine breather through the oil separator.
I tried cleaning out all of the air pipes and the separator but the oil returned almost immediately.
I did think about buying a new oil seperator but as it's a simple cyclonic system, without any filter or moving parts as far as I can see, I thought a new one might not be any better.
Does anyone have ideas to remedy this situation?
Thanks
