This crankcase ventilation valve is for the specified Opel Z22YH applications. A faulty ventilation valve can disturb crankcase pressure, admit unmetered air and contribute to unstable idle or increased oil consumption.
Vehicle Applications
- Opel ASTRA-H Z22YH - from 2004.
- Opel SIGNUM Z22YH - 2003-2008.
- Opel VECTRA-C Z22YH - 2002-2008.

When to Inspect Crankcase Ventilation
- Whistling or excessive crankcase vacuum.
- Unstable idle.
- Increased oil consumption.
- Oil deposits in the intake.
- Exhaust smoke after warm-up.
- Mixture faults associated with unmetered air.
These symptoms call for inspection of the ventilation valve and housing; they do not establish the cause on their own.

Inspection Before Replacement
