Abstract
Methods and systems are provided for ventilating a crankcase in a boosted engine. An example method may include selectively enabling one of crankcase ventilation and aspirator motive flow via an electrically controlled valve, the aspirator motive flow being enabled in response to a demand for vacuum from a vacuum consumer. In this way, the crankcase of the boosted engine may be ventilated until the vacuum consumer demands vacuum.
