REMOVAL & INSTALLATION



For a complete explanation of the Positive Crankcase Ventilation (PCV) system, refer to Driveability & Emission Controls of this repair guide.

Since a clogged PCV valve or hose can adversely affect idle quality or engine performance, be sure to replace the PCV valve at least every 50,000 miles (83,000 km). The PCV valve is threaded into the intake manifold, near the cylinder head cover, on the 1.3L and 1.6L 8-valve engines, and is installed in the cylinder head cover on the 1.6L 16-valve and 1.8L engines. To replace the PCV valve, perform the following:

1.3L and 1.6L 8-Valve Engines

  1. Detach the PCV system hoses from the cylinder head cover, PCV valve, air cleaner assembly and the 3-way junction.
