Ford Focus PCV Valve Parts Questions & Experts Answers
- Q: Where is the location and how to replace the PCV valve and PCV filter in a Ford Focus?A: Most covered models have the PCV valve in the crankcase ventilation oil separator, low on the engine. Find it by following the PCV Hose from the air cleaner housing. On 2.0L SPI engines, the PCV valve is in the valve cover. Before removing it, let the engine cool. On SPI engines, disconnect the PCV hose from the valve, then twist it out of the valve cover grommet. On 2.3L and 2005 2.0L models, raise the front of the vehicle and remove the under-engine splash shield. Remove the intake manifold for access to the PCV valve. Disconnect the hose from the valve at the oil separator. Push in the tabs and twist the PCV valve out. On all models, test the valve by shaking it. If it doesn't rattle, replace it. For PCV filter replacement, remove the air cleaner cover. Pull the PCV filter out of its pocket in the air cleaner housing. The PCV system air filter is in the air cleaner housing - remove the air filler for access. Inspect the filter and replace if clogged or damaged.
- Q: How to remove and install the crankcase emission control system and PCV Valve on Ford Focus?A: The crankcase emission control system, also known as positive crankcase ventilation (PCV), consists of hoses connecting the crankcase to the air cleaner or Intake Manifold. Some engines have oil separator units located at the left-hand end or front of the engine. The system requires regular checking for blockages and damage to the hoses, valve, and oil separator. To remove the PCV valve, trace the ventilation hose to the valve and disconnect it. The valve can then be pulled out. If the hose is damaged, the thermostat housing may need to be removed for access. Wash the valve in a suitable solvent and ensure all passages are clear. Check the hoses for damage, especially at the ends, and inspect the condition of the O-ring if present. Installation is the reverse of removal, ensuring secure and correct hose installation. The oil separator is located behind the Exhaust Manifold and Catalytic Converter on the front of the engine block. Access requires removing the manifold and converter. Disconnect the hose or remove the PCV valve. The separator is secured by three bolts, which should be unscrewed to remove the separator and recover the gasket. If not already done, remove the PCV valve from the separator and wash the separator with a suitable solvent. Ensure clear passages and use a new gasket when reinstalling the separator, tightening the bolts securely.
