Description
Oil vapor breather tube for Citroën and Peugeot 2.0 HDI RH02 engines. The yellow split pin may be missing.
This oil vapor breather tube is a direct-fit replacement part designed for Citroën and Peugeot 2.0 HDI RH02 applications. Suitable for professional workshops and DIY mechanics, the tube restores correct crankcase ventilation, prevents oil accumulation in the intake tract and ensures reliable turbo and engine performance. Often searched by part code 1192CC or engine code RH02, this component is an economical and fast way to eliminate vacuum leaks, oil smells in the intake and related drivability issues.
Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: 2.0 HDI RH02
- Product Codes: 1192CC
- Additional Numbers: No additional OE numbers provided
Fitment
Typical vehicle applications include:
- Citroën C4 Picasso
- Citroën C8
- Peugeot 3008 I
- Peugeot 5008 I
- Peugeot 807
Function
The breather tube connects the crankcase ventilation system to the intake, routing oil vapors back into the combustion process. This reduces crankcase pressure, minimizes oil leakage and prevents excessive oil from entering the turbo and intercooler. A damaged or leaking breather tube can cause rough idle, increased oil consumption and oil deposits in the intake system.
Replacement And Maintenance
Replacement is straightforward for a trained technician or an experienced DIY mechanic. General procedure:
- Allow Engine To Cool And Work In A Well-Ventilated Area.
- Remove Any Engine Covers Or Intake Ducting Obstructing Access To The Tube.
- Loosen Clamps Or Fasteners At Both Ends Of The Tube And Withdraw The Old Tube.
- Inspect Mating Ports For Oil Residue Or Debris And Clean As Needed.
- Install New Tube, Fit Clamps Securely And Replace Any Missing Retaining Pins (Note: The Yellow Split Pin May Be Missing).
- Start Engine And Check For Vacuum Leaks, Oil Smells And Proper Idle.
Inspect the breather tube and associated hoses during regular maintenance intervals and whenever oil is found in the intake or turbo system.
Installation Recommendations
- Use New Clamps And Correct-Size Hose Clips To Ensure A Leak-Free Seal.
- Replace Associated Seals Or Grommets If They Appear Worn.
- Check The Intake And Turbo Piping For Oil Contamination; Clean Or Replace Components As Required.
- Follow Manufacturer Service Procedures And Torque Specifications For Any Removed Fasteners.
Most Common Failure Reasons
Breather tubes typically fail due to heat aging, oil contamination and mechanical stress. Over time rubber or plastic sections harden, crack or split, causing vacuum leaks and allowing unmetered air or oil into the intake. Excessive blow-by from worn piston rings or a clogged PCV system accelerates oil saturation and shortens the tube’s service life.
For mechanics and competent DIYers this replacement is a low-cost, high-impact repair that often resolves unacceptable idle, oil in the intake tract and turbo performance loss.
