Standard Motor Products 47044 PCV System Elbow is a replacement PCV elbow for 1987–1991 Ford and Mercury 5.8L engines. This component is part of the positive crankcase ventilation system, designed to route crankcase vapors from the valve cover through the PCV path to the intake, helping maintain proper engine vacuum and emissions control on these applications. The part number 47044 identifies the elbow used on 87–91 5.8L engines, providing a compatible option for restoring PCV system function in affected vehicles. Use of this elbow supports consistent engine performance by keeping the PCV circuit intact in older Ford/Mercury 5.8L powerplants.
