Description
Crankcase breather pipe for Citroën and Peugeot vehicles with 2.0 HDi engine. Oil vapour connection.
Product Overview
This breather pipe (oil vapour connection) is designed for 2.0 HDi diesel engines fitted to a range of Citroën and Peugeot models. The part routes crankcase vapours from the oil separator/PCV system back into the intake tract or the turbo inlet, helping to control oil emissions and maintain proper crankcase ventilation. Supplied as an OE-cross reference part number 1192Z7 for cost-effective replacement and direct fit on compatible vehicles.
Key Benefits
- Direct fit for 2.0 HDi engines — easy replacement with original routing and connections.
- Reduces Oil Contamination In The Intake — helps prevent oil deposits on the throttle body and intercooler.
- Cost-Effective Repair — restores correct crankcase ventilation and reduces smoke/oil consumption symptoms.

Replacement Procedure (Overview)
Replacement is straightforward for a competent mechanic or experienced DIYer. Typical steps:
- Allow Engine To Cool. Remove Any Engine Covers Or Air Intake Components Blocking Access.
- Locate The Breather Pipe Between The Oil Separator/PCV Assembly And The Intake/Turbo Inlet.
- Loosen Clamps Or Remove Fasteners Securing The Pipe. Carefully Withdraw The Old Pipe To Avoid Spilling Oil Residue.
- Fit The New Pipe Ensuring Correct Orientation And Secure All Clamps. Replace Damaged Clamps Or Seals If Necessary.
- Reassemble Intake Components, Start Engine And Check For Leaks, Unusual Noises Or Fault Codes.
Installation Recommendations
- Inspect The Oil Separator/PCV Valve For Sludge Or Blockage While Replacing The Pipe.
- Replace Any Brittle Hose Clips Or Grommets To Ensure A Reliable Seal.
- Do Not Overtighten Clamps — Secure Firmly But Avoid Deforming The Pipe.
- Clean Oil Residue From Throttle Body And Intake Components If Present To Restore Proper Airflow.
- For Long-Term Reliability, Consider Inspecting The Entire Crankcase Ventilation System At Regular Intervals.
Why The Part Most Commonly Fails
- Ageing And Heat Exposure — Rubber Or Plastic Materials Harden And Crack Over Time.
- Oil Sludge And Contamination — Build-Up Can Clog The Pipe Or Cause Restrictions.
- Vacuum Or Pressure Spikes — Can Deform Flexible Sections Leading To Collapse.
- Previous Repair Damage — Improperly Routed Or Clamped Hoses Wear Prematurely.
Recommended Inspection Interval
There Is No Fixed Replacement Interval For The Breather Pipe. Inspect The Hose And The PCV System During Routine Services, Especially On High-Mileage Engines Or If You Observe Any Of The Symptoms Listed Above.
Notes For Mechanics And DIYers
Part Number 1192Z7 Is A Direct Reference For Many 2.0 HDi Applications. When Replacing The Pipe, Verify Access To The Oil Separator And Check Surrounding Hoses And Clamps To Prevent Repeat Failures. This part is a practical, cost-effective way to resolve crankcase ventilation problems that lead to oil consumption and intake contamination.
