  4. Crankcase Pressure Regulator Valve (Oil Separator)

    Crankcase Pressure Regulator Valve (Oil Separator)

    The crankcase-ventilation oil separator, or CVV, recirculates the small — but continual — amount of blow-by, created by gases leaking past the rings in the combustion chamber. Over time, the CVV valve can become clogged or crack, causing oil leaks and oil to be pushed back and burnt in the combustion chamber — a less than ideal situation.

  5. Upper Oil Separator Vent Tube

    Upper Oil Separator Vent Tube

    This vent tube runs from the top of the oil separator to the back of the intake manifold. An unfortunate and ongoing issue with modern BMWs is with the oil separator, or CVV system. Over time, the oil vapours the system is designed to capture and recirculate can cause clogged lines and other blockages, resulting in oil leaks, or the engine to run poorly.
