Designed for professional workshops and competent DIY mechanics, the assembly includes both exhaust and intake cam components supplied as a matched set to restore correct valve timing and lift characteristics on affected engines.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: 1.4 HDi 16V 8HY, 66 kW
- Product Codes: 0801Z9, 0801AH
- Other Numbers: Engine Code 8HY; Common Fitment Examples: Citroën C3, Peugeot 1007
Application And Compatibility
Fits 1.4 HDi 16V 8HY engines rated at 66 kW. Typical vehicle applications include Citroën C3 and Peugeot 1007 models equipped with the 1.4 HDi 8HY engine. Buyers frequently locate this part by searching the product codes 0801Z9 or 0801AH—include these numbers when checking fitment.
Product Description And Benefits
The assembly contains the intake and exhaust camshafts matched for timing and valve lift, ensuring correct valve operation and combustion efficiency. Replacing worn or damaged camshafts restores engine smoothness, improves responsiveness, and prevents misfires or rough idling caused by irregular valve timing. This unit is suitable for head overhauls, timing system repairs, and restorations where cam wear or damage has been identified.
Installation Recommendations
- Replace During Major Timing Service: Install the camshaft assembly when performing timing belt/chain or cylinder head work to ensure long-term reliability.
- Follow Manufacturer Timing Procedure: Align all timing marks precisely and set valve timing according to the official service manual for the 1.4 HDi 8HY engine.
- Use New Ancillary Parts: Replace timing belt/chain, tensioner, idler pulleys, and camshaft seals when installing the assembly to avoid secondary failures.
- Clean Work Area: Ensure the head, bearing journals, and lubrication passages are clean before assembly to prevent premature wear from contamination.
- Verify Operation: After installation, rotate the engine by hand through at least two full revolutions and recheck timing marks and clearances before first start.
Common Causes Of Failure
Camshaft assemblies typically fail due to oil contamination or insufficient lubrication, long service intervals with degraded oil, and secondary damage from timing-belt or tensioner failure. Excessive wear, scored lobes, or broken cam lobes can arise from neglected oil changes, foreign particles in the lubrication system, or sudden mechanical shock when a timing component fails.
Notes For Mechanics And DIY
When ordering, confirm part numbers 0801Z9 or 0801AH to match the replacement to the vehicle. While this assembly is intended as a direct fit for specified engines, always follow the vehicle manufacturer’s workshop manual for disassembly and torque specifications. Inspect related components (cam followers, rocker arms, lifters, and valve guides) when replacing camshafts to ensure complete restoration of valve train performance.
Fast identification by part number and correct installation will help return the 1.4 HDi engine to reliable service and avoid repeat visits for valve-train related issues.
