    Q:
    Why is a PCV system necessary in gasoline engines for the 1989 Cadillac ElDorado? Posted by Customer
    A:
    In gasoline engines, small amounts of combustion gas leak past the piston rings into the crankcase, which contains undesirable hydrocarbon air pollutants. The PCV system prevents these vapors from escaping into the atmosphere.
