The checks worth doing on a Holden Statesman before you hand over any money. Every documented fault is listed below, each with its own page.

• Serious issue

  Check for oil leaks around valve covers, sump and gaskets.

  L76 AFM Hydraulic Lifter Collapse

  The L76 6.0L V8 fitted to WL Statesman and Caprice uses Active Fuel Management (AFM/DoD), which relies on hollow hydraulic lifters to deactivate cylinders 1, 4, 6 and 7 under light load. These lifters are prone to hydraulic collapse, typically between 80,000 and 140,000 km. When a lifter fails catastrophically it sheds metal fragments that circulate through the oiling system, contaminating rod and main bearings, scoring cam lobes and cylinder walls. Engines that have ingested debris almost always require a full bottom-end rebuild or engine replacement in addition to the AFM delete. The definitive repair is a preventive or reactive AFM delete: solid replacement lifters, a non-AFM camshaft, a block-off plate over the AFM valley solenoids, and an ECU retune to remove cylinder-deactivation logic. Engines with no evidence of prior debris contamination can be deleted without a rebuild; those with metal in the sump invariably cannot.

  What you would notice

  • Evidence of engine wear or deterioration
  • Warning light or abnormal behaviour noted during operation

  Typically $5,950–$11,900 to put right.

• Serious issue

  During test drive at highway speed, confirm smooth and positive 3-4 upshift.

  4L60E Automatic 3-4 Clutch Pack Failure

  The 4L60E four-speed automatic transmission used in WH, WK, and WL Statesman is prone to 3-4 clutch pack wear and failure. The 3-4 clutch pack engages third and fourth gear; when worn, the transmission slips between these gears or drops out of fourth entirely under load. Overheating from sustained highway driving or occasional towing accelerates failure. A full rebuild or replacement transmission is typically required.

  What you would notice

  • Slipping or flaring when shifting from 3rd to 4th gear at highway speeds
  • Transmission dropping out of 4th gear under moderate throttle
  • Delayed or harsh engagement from rest when cold
  • Burnt transmission fluid odour
  • Transmission fault codes P0732 or P0733

  Typically $2,500–$5,000 to put right.

• Serious issue

  Check the dipstick is at full before you drive - this engine punishes low oil.

  See why

  5.7 LS1 V8 oil starvation from the local sump / no low-oil warning

  The V8 WH/WK Statesman uses the 5.7 LS1, but the Australian cars were fitted with a local sump that deleted the low-oil-level warning light the US engines had, and positions the oil pickup at the front of the sump. If the oil is a bit low, hard acceleration or a firm stop can uncover the pickup and let it suck air, and even a short run with low oil can starve and wreck the bottom-end bearings. Because there's no warning light, an owner can run it low without knowing. These engines can also show light 'piston slap' rattle on cold start, which is usually cosmetic.

  What you would notice

  • Deep knocking from the bottom of the engine (bearing damage)
  • Light metallic rattle on cold start that fades when warm (piston slap - usually harmless)
  • Low oil on the dipstick
  • Oil-pressure warning under hard driving or braking

  Typically $3,000–$9,000 to put right.

• Costly issue

  Start the engine from cold and listen for a rattle from the timing (front) end that quietens after a few seconds.

  See why

  3.6 Alloytec/SIDI V6 timing chain stretch from oil sludge

  The 3.6 V6 (Alloytec LY7, later SIDI) in the WM/WN Statesman is prone to timing chain stretch, and the root cause is oil sludge from skipped or extended oil changes clogging the tensioners and starving the chain of clean oil. A stretched chain sets off a rattle (especially on start-up) and a check-engine light for camshaft timing correlation, and if ignored it can jump timing and damage the engine. Repair means chains, guides, tensioners and usually the oil pump - a big job.

  What you would notice

  • Rattle from the front of the engine, worst on cold start-up
  • Check-engine light for camshaft/crankshaft correlation
  • Loss of power or rough running
  • History of missed oil changes / sludgy oil

  Typically $1,800–$4,500 to put right.

• Costly issue

  Check rear ride height visually — should sit level or near-level with the front.

  See why

  Rear Air Suspension Compressor and Air Bag Failure

  WK and WL Statesman models fitted with optional rear self-levelling air suspension suffer from rubber air bag perishing and compressor motor burnout. The rubber bags crack at fold lines with age, causing the rear to sag. When the compressor runs continuously to compensate, the motor overheats and fails. Replacement is available but the proprietary system involves significant workshop time, and many owners convert to coilover springs.

  What you would notice

  • Rear of vehicle sitting visibly lower than the front
  • Vehicle rising slowly after start then sagging again within minutes
  • Air compressor motor running audibly and continuously from boot or underfloor
  • Rear suspension bottoming out over bumps
  • Ride height or suspension warning light on instrument cluster

  Typically $1,200–$3,000 to put right.

• Costly issue

  Cold-start the engine and watch exhaust for blue smoke.

  See why

  LS1 5.7L V8 Valve Stem Seal Oil Consumption

  The LS1 5.7L V8 fitted to WH, WK, and WL Statesman suffers from hardening valve stem seals with age. Hardened seals fail to contain oil at the valve stem, allowing oil to be drawn into the combustion chamber, particularly on overrun. Oil consumption is progressive and can exceed 1L per 1000km on high-mileage examples. Replacement requires the engine to be in-situ with valve springs compressed individually.

  What you would notice

  • Blue-grey smoke from exhaust on overrun after sustained highway driving
  • Blue smoke on cold start that clears after warm-up
  • Oil consumption above 500ml per 1000km
  • Fouled spark plugs with oil deposits on inspection
  • Oil smell from exhaust at operating temperature

  Typically $800–$2,000 to put right.
