Solid 5.0-litre V8 (naturally aspirated, no supercharger). Timing chain and guides are the known weak point from around 130,000 km. Short oil change intervals (max. 8,000 km) significantly reduce the risk. Replace plastic coolant pipes preventively with aluminium items. Character: refined V8 with decent power delivery.
5.0 V8 Range Rover L322: classics among themselves
The 5.0-litre V8 naturally aspirated in the L322 is the forerunner of all modern Range Rover V8s. More refined than expected, with rich acoustic qualities at full throttle. For L322 enthusiasts the finest engine in the range — with the well-known chain costs.
Engine Weaknesses 4
The AJ133 5.0L V8 (naturally aspirated) is known for premature wear of the plastic timing chain guides and hydraulic tensioners. The fault typically appears from 120,000–150,000 km. Extended oil change intervals are a frequent contributing factor.
Symptoms: Rattling/knocking on cold start, P0008/P0016/P0017, engine light, power loss
Like the supercharged V8, the naturally aspirated V8 has numerous plastic coolant pipes and fittings that become brittle and crack. Pre-emptive replacement with metal pipes (Euro AMP kit) is strongly recommended.
Symptoms: Sudden coolant loss, overheating warning, steam from the engine bay
Ignition coils on the 5.0 V8 tend to fail, often in combination with oil-fouled spark plugs (caused by valve stem seals). Rough running and misfire codes on multiple cylinders simultaneously are typical.
Symptoms: Rough running, P030X misfire codes, engine light, oil-fouled spark plugs
Valve stem seals on the 5.0 V8 (NA) wear out and allow oil into the combustion chamber. Oil-fouled spark plugs and blue smoke on cold start are typical symptoms. Repair requires extensive engine disassembly.
Symptoms: Blue smoke on cold start, oil-fouled spark plugs, elevated oil consumption >0.5L/1000km
Vehicle Weaknesses 8
Wabco or Hitachi compressor loses output pressure due to worn piston rings. Vehicle drops after parking, slow rise, compressor runs continuously. Repair kits available; new compressor approx. 700–900 euros. Regarded as the most common fault on the L322.
Steel body rusts at the rear wheel arches, sills and tailgate. Water collects at the lower tailgate edge and leads to blistering and rust-through. Sill area and running boards are also typical problem zones.
ECUs are located under the front seats and in the engine bay — immediately at risk when water enters through a leaking windscreen or sunroof. Cascading fault messages from air suspension, gearbox and ABS are often a consequence of floor dampness.
ZF 6HP automatic shows gear kick, delayed engagement and torque converter issues when oil changes are skipped. Sensor no longer detects park position. Gearbox oil should be changed every 60,000 km.
Handbrake drum seizes from corrosion; countersunk drum screws corrode and are almost impossible to remove. Actuator module jams with worn drums. Fault code C1A00, brake force sensor shows extreme values. Specialist tool required to release.
Electric steering column adjustment uses plastic components that break when operated. Repair is possible at lower cost using alternative parts. After that, no electric adjustment is possible; steering effort and steering itself are undamaged.
Wiring harness for the rear parking sensors in the rear bumper corrodes from moisture. Control unit fails or sensors themselves drop out. Corroded contacts in the bumper area are the most common cause of PDC failure.
Air conditioning condenser and connecting hoses lose refrigerant due to age and vibration. Air conditioning only blows warm air. Topping up without finding and fixing the leak is only a short-term remedy.
