All Known Issues

1.4 and 1.6 VVT-i Engine Oil Consumption from Ring Sticking

SeriousEngine

Early UK-built 1.4 (4ZZ-FE) and 1.6 (3ZZ-FE) VVT-i petrol engines produced between 2002 and 2004 are prone to excessive engine oil consumption. Undersized oil drain holes in the piston skirts become blocked by carbonised oil, causing the oil control rings to stick and burn oil at rates exceeding one litre per 1,000 miles. Left unchecked, the engine runs low on lubricant, leading to timing chain wear and crankshaft bearing damage. Toyota UK replaced affected engine short blocks under warranty.

Est. Repair Cost: £600–£1,400
Warning Signs:

Engine oil level drops rapidly on dipstick between routine annual service checks, Black carbon sooty deposits around the exhaust tailpipe opening, Blue smoke haze emitted from the exhaust during hard acceleration or overrun, Ticking or rattling noise from the timing chain caused by low oil pressure

What to Inspect:
  • Pull the engine oil dipstick and check the oil level and color prior to test driving
  • Inspect vehicle history for stamped warranty engine replacement paperwork from a Toyota dealer
  • Check the exhaust for blue smoke while an assistant revs the engine to 3,500 rpm

Air Conditioning Condenser Stone Damage and Gas Leakage

MinorCooling System

The air conditioning condenser is mounted at the very front of the cooling pack, directly behind the wide open slats of the lower front bumper. Road gravel and stone chips thrown up on UK roads strike the fragile aluminium tubes, causing punctures and gradual loss of R134a refrigerant gas. Without refrigerant, the compressor clutch disengages and the cabin ventilation blows only ambient warm air.

Est. Repair Cost: £220–£450
Warning Signs:

Air conditioning fails to blow cold air even when the A/C button light is illuminated, Hissing noise heard from the dashboard centre air vents when activating the air conditioning, Oily green UV dye or dark damp dirt staining visible on lower condenser cooling fins, Air conditioning compressor clutch fails to engage when temperature dial is set to cold

What to Inspect:
  • Switch ventilation to maximum cold and verify ice-cold air flows within 60 seconds of operation
  • Shine a torch through the lower bumper intake to inspect the condenser fins for stone damage or corrosion
  • Check service records for recent air conditioning regas history that may mask an active leak
