Keep crankcase vapors flowing along their intended path with the Standard Ignition PCV Valve V233. It drops in as a direct-fit replacement for a wide range of Ford, Mercury, Infiniti and Nissan applications, including the 1992 Ford Thunderbird, 1993-1998 Mercury Villager, 1990-1992 Infiniti M30, 1997-2000 Infiniti QX4, 1984-1989 Nissan 300ZX, 1985-1994 Nissan Maxima, 1987-2000 Nissan Pathfinder and 1999-2004 Nissan Frontier — see the Buyer's Guide tab for the full list.
A PCV (positive crankcase ventilation) valve meters blow-by gases from the crankcase back into the intake, helping regulate crankcase pressure and route vapors through the emissions system rather than venting them.
Signs the original may need replacing include a rough idle, oil leaks, or oil sludge — if a failed PCV valve is the cause, this replaces it. Diagnose the cause before replacing.
