Description
Exhaust Manifolds 1.1 and 1.4 and 1.6 8V CITROËN PEUGEOT
Exhaust Manifold
Direct-fit exhaust manifold designed for petrol 1.1, 1.4 and 1.6 8V engines used across selected Citroën and Peugeot models. This robust collector channels exhaust gases from the cylinder head to the downpipe and catalytic converter, restoring exhaust flow, reducing leaks and preventing loss of torque. The manifold is commonly referenced by OEM numbers and aftermarket codes, which helps technicians and DIYers find the correct replacement quickly.

Function And Benefits
The exhaust manifold collects exhaust gases from the engine cylinders and routes them into the exhaust system. A properly sealed and undamaged manifold ensures correct backpressure and protects upstream sensors (O2 sensors) and the catalytic converter. Replacing a worn or damaged manifold eliminates ticking leaks, reduces cabin fumes and can improve drivability and fuel efficiency.
Typical Symptoms Indicating Replacement
- Sharp ticking or tapping noise from the engine bay on cold start that may change with engine speed.
- Exhaust smell or fumes near the front of the vehicle.
- Reduced engine performance or irregular throttle response.
- Check engine light related to oxygen sensor readings or misfires (codes may indicate downstream effects).
Why This Part Typically Fails
Exhaust manifolds are exposed to extreme temperature cycles and corrosive gases. Common causes of failure include thermal fatigue leading to cracks, gasket deterioration, corrosion from road salt and moisture, and seized or snapped studs/bolts from long-term heating and cooling. Improper installation or repeated overheating can accelerate damage.
Installation Recommendations
For reliable replacement and long-term performance follow these recommendations:
- Work on a cold engine. Allow the exhaust system to cool fully before starting.
- Remove any heat shields and support the exhaust downstream (downpipe/catalytic converter) to avoid undue stress on the new manifold.
- Disconnect oxygen sensors before removing the manifold; protect sensors from damage and contamination.
- Always fit a new exhaust manifold gasket and, where applicable, replace studs, nuts or bolts with new fasteners. Apply suitable anti-seize to bolts where recommended by manufacturer.
- Clean and inspect mating surfaces on the cylinder head and downpipe. Ensure surfaces are flat and free of carbon or corrosion before assembly.
- Tighten fasteners gradually in the correct sequence to ensure even sealing. Follow manufacturer torque specifications when available.
- After installation, start the engine and check for leaks; re-torque fasteners after the first heat cycle if required by the workshop manual.
- Use penetrating oil and care when removing old fasteners—studs can be brittle and may require extraction tools.
Replacement Interval
There is no fixed interval for exhaust manifold replacement. Lifespan depends on driving conditions, climate (salted roads shorten life), and maintenance. Many manifolds last the life of the vehicle, but signs of leakage or cracking warrant immediate replacement to prevent further engine or exhaust-system damage.
Fitment And Compatibility
This manifold is intended for the listed Citroën and Peugeot models with 1.1, 1.4 and 1.6 8V petrol engines. Searching by product codes 9661916480 or 0341F9 is a common and effective way to locate the correct unit for your vehicle.
Order this exhaust manifold to restore proper exhaust sealing and engine performance. Suitable for professional workshops and competent DIY mechanics familiar with exhaust-system procedures.
