Main faults, breakdowns and problems of the 1G-GE engine
The 1G-GE engine is one of the most reliable among Toyota motors of its time. However, it can have some problems at high mileage:
- Reliability and life
The engine is known for its durability and with regular maintenance, it can go 400,000 kilometers or more without any problems. - Oil consumption at high mileages.
At high mileages, you may experience increased oil consumption due to piston ring seizure. This can be corrected by replacement or repair. - Swimming RPMs
The main cause of erratic idle speeds is a dirty throttle plate or malfunctioning idle speed regulator (idle control valve). - Oil pressure sensor
Some owners complain of oil pressure sensor failures or oil leaking from under the sensor, which may require replacing the gasket. - Lack of hydrocompensators
The engine is not equipped with hydrocompensators, so it is important to check valve clearances regularly, every 20,000 km.
The Toyota 1G-GE is a reliable and unpretentious engine that, when properly maintained, provides long life and excellent performance.
