Motorcraft EV297 is a direct-replacement PCV valve for many Ford and Lincoln engines, restoring controlled crankcase ventilation by routing blow-by gases back into the intake system. Correct PCV flow helps manage crankcase pressure, supports emissions control, and helps limit oil contamination and sludge buildup on verified 2010-2026 applications such as F-150, Bronco, Edge, Expedition, Explorer, Mustang, Navigator, Aviator, and Transit vans.
