Keep your crankcase venting the way the factory intended with the Standard Ignition PCV Valve V390. This positive crankcase ventilation valve installs as a direct-fit replacement for the 2005 Ford Escape (L4-2.3L), 2003-2005 Ford Focus (L4-2.3L), 2004-2005 Ford Ranger (L4-2.3L), 2011 Mazda 3 (L4-2.3L), 2010-2012 Mazda 3 (L4-2.5L), 2003-2005 Mazda 6 (L4-2.3L), 2009-2012 Mazda 6 (L4-2.5L), 2004-2009 Mazda B2300 (L4-2.3L), 2011-2012 Mazda CX-7 (L4-2.5L), 2005-2006 Mazda Tribute (L4-2.3L), and 2008 Mazda Tribute (L4-2.3L).
- Regulates crankcase ventilation: meters the flow of blow-by vapors from the crankcase into the intake so they can be re-burned rather than building up pressure.
- Spring-loaded valve: opens and closes with changes in intake vacuum to control the ventilation flow across engine operating conditions.
- Direct-fit service part: designed to install in place of the original PCV valve on the listed applications.
A stuck or clogged PCV valve can allow crankcase pressure to build, and signs it may need replacing include rough idle, oil seepage past seals, or increased oil consumption. Diagnose the cause first; if a failed PCV valve is behind the symptom, this replaces it.
Interchange: Manufacturer part number V390.
