Crankcase Ventilation
WARNING: This page is about a different car, the 1995 Dodge Pickup and 1995 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
Crankcase ventilation on 8.0L engine does NOT use a PCV valve. System consists of a fixed orifice (Gray color) that is calibrated to a specific flow rate. The fixed orifice (located on intake manifold) is connected by a tube to right valve cover. A similar orifice is used on left cylinder head, but is Black in color and cannot be interchanged with Gray orifice. Ensure orifice, tubes and fittings are clean and in good condition. No further information is available.
