- Period mentioned
- Approx. 1998–2005
- Symptoms
- Oil must be topped up between changes (more than a litre every 1,600 km in bad cases), bluish smoke and fouled spark plugs; eventually misfires and a damaged catalytic converter.
- Possible cause described
- The piston rings on early engines stuck and let oil into the combustion chamber. Toyota changed the pistons in July 2005 and extended the engine warranty in the US.
- Check for the garage
- Measure consumption between two changes with the level set correctly and check the spark plugs and catalytic converter. If consumption is high, the lasting fix is new pistons and rings.
