Crankcase Ventilation Hose — Opel 1.7D Diesel | Astra, Corsa, Meriva, Zafira
Stop Oil Mist Leaks and PCV Faults on Your Opel 1.7 Diesel — One Cheap Hose Does It.
A cracked or brittle crankcase ventilation hose on your Opel 1.7D causes oil mist to escape into the engine bay, triggers PCV fault codes, and can contaminate the intake and throttle body. This is a direct OEM-spec replacement hose that restores proper crankcase ventilation in minutes.
Why Replace the PCV Hose
- Stops Oil Mist Leaks: A split hose allows crankcase gases and oil mist to escape — dirtying the engine bay and contaminating the intake.
- Clears PCV Fault Codes: A failed hose often triggers check-engine codes related to crankcase ventilation pressure.
- Protects the Throttle Body: Oil mist routed through a damaged hose coats the throttle body and EGR — accelerating deposits and wear.
- Cheap Preventive Fix: One of the lowest-cost maintenance items on the 1.7D — replace it before it causes secondary damage.

Pro Tip: On 1.7D engines, PCV hose failure is often the cause of oil residue around the valve cover area and an oily film inside the air intake. If you're cleaning the throttle body regularly, inspect the PCV hose — it's probably the root cause.
