So, that small spring and rubber cap create a seal until the pressure is enough to push it up and let it vent through?
If the inside of the hoses to and from the turbo are covered in oil, then it sounds like it's pushing oily vapour through the cyclone breather. If that's the case it will be burning a certain amount of oil. The dark smoke coming out of the exhaust could also be poorly burnt fuel, so perhaps your fuel injection pump has been tweaked?If it smokes the smoke is dark, but I can hardly say it is using “oil” and no cooling water.
That is already this way over a 100k, I bought the engine with 160k (kilometers) on the klok.

Oil inside the breather hoses sounds perfectly normal to me, that is after all their function as every engine naturally breathes, to return any oil droplets from the oil mist to the sumpIf it smokes the smoke is dark, but I can hardly say it is using “oil” and no cooling water.
