• Product Codes: 9684193080, 9686975480, 0320AJ
• Additional Numbers: 0320CH

Function And Benefits

• Protects Timing Components: Shields the belt/chain, tensioner and camshaft seals from contaminants and mechanical damage.
• Sealing Interface: Provides mounting surfaces for gaskets and oil seals to prevent oil leakage from the timing cover area.
• Direct Fit: Designed to match original mounting points and clearances for hassle-free installation on compatible 1.6 HDi 8V engines.
• Improves Reliability: Replacing damaged or worn covers during timing-system service reduces the risk of oil leaks and premature belt/chain wear.

Replacement Procedure (Overview)

Removal and installation should be performed by an experienced mechanic or competent DIYer with basic engine experience. Typical steps:

• Remove engine covers and ancillary components obstructing access (air intake ducts, accessory brackets, belts as required).
• Support the engine if required and relieve any tension from the timing belt/chain according to the manufacturer procedure.
• Unbolt the upper timing cover, carefully detach old gasket or sealant, and inspect mounting faces for damage or corrosion.
• Fit a new gasket or approved sealant, position the new cover and tighten bolts to manufacturer torque sequence and values.
• Reassemble removed components, restore belt/chain tension where applicable, start the engine and check for leaks and correct operation.

Installation Recommendations

• Always Replace Seals/Gaskets: Install a new gasket and, where applicable, a new camshaft oil seal when fitting the cover to ensure a reliable seal.
• Clean Mating Surfaces: Remove old sealant and debris; ensure surfaces are dry and oil-free before assembly.
• Follow Torque Specs: Use the manufacturer’s bolt torque values and tightening sequence to avoid warping or leaks.
• Inspect Related Components: Check timing belt/chain, tensioner, idlers and pulleys while access is available; replace if worn.
• Safety: Wear appropriate PPE and use proper tools; if engine support is required, secure the vehicle on axle stands and follow safe lifting practices.

Most Common Failure Reasons

• Aged Plastic And Cracking: Repeated heat cycles and vibration can cause plastic covers to become brittle and crack, leading to contaminant ingress or mechanical damage.
• Gasket Or Seal Deterioration: Oil leaks commonly originate from a degraded gasket or damaged camshaft seal at the cover interface.
• Impact Or Mechanical Damage: Damage during previous repairs or from debris can deform the cover or break mounting tabs.
• Improper Installation: Over-tightening bolts or incorrect sealing can cause leaks or premature failure.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: 1.6 HDi 8V
• Product Codes: 9673568180, 0320CH
• Additional Numbers: 0320CH | 9673568180

Function and Benefits

The upper timing cover shields the timing mechanism (belt/chain area depending on specific engine variant) and associated components such as camshafts, tensioners and seals. It prevents ingress of dust and debris, limits oil spray to the engine bay and helps maintain proper lubrication of timing components. A correctly fitted cover supports reliable timing system operation and contributes to longer life of belts, tensioners and seals.

Replacement and Installation

General replacement steps for workshops or experienced DIYers:

• Disconnect the battery before starting work.
• Remove any decorative engine covers and ancillary components that obstruct access to the timing cover (air intake ducting, sensor connectors, hoses as required).
• Carefully unbolt the upper timing cover, noting bolt positions and any plastic clips to avoid breakage.
• Remove the old gasket or sealing material and thoroughly clean mating surfaces. Replace the gasket/seal as required.
• Fit the new cover, align mounting points, and tighten bolts to the manufacturer’s torque specifications.
• Reinstall removed components, reconnect the battery and start the engine to check for abnormal noises or oil leaks.

Always follow the vehicle manufacturer’s repair manual for exact removal order, bolt torque values and any special procedures.

Installation Recommendations

• Replace the sealing gasket or O-rings when fitting the new cover to ensure leak-free installation.
• Inspect mounting tabs and surrounding components for damage; broken tabs are a common issue and can complicate fitting.
• Use new fasteners or clips if the originals are stretched or damaged.
• Clean mating surfaces thoroughly—old sealant or residue can cause leaks.
• If replacing during a timing service, inspect the timing belt/chain, tensioners and water pump and consider replacing wear items together.

Common Failure Causes

• Ageing and heat exposure cause plastic covers and mounting tabs to become brittle and crack.
• Impact or improper removal leading to broken clips or tabs.
• Degraded gaskets/seals result in oil leaks that can contaminate the timing belt area and accelerate wear.
• Improper installation or loose fasteners permit ingress of dirt and moisture, leading to premature wear of timing components.
