Toyota G series engines are 6-cylinder in-line engines. They began in 1979 and lasted until 2006. A special feature of the G series is the fact that it lacks a variety of engine sizes. All engines have the same displacement of 2 liters (1988 cc). The drive of the gas distribution system of all engines of the series was carried out using a timing belt.

— official information
- Fast consumption of engine oil. The reason lies in the sinking of the oil scraper rings, which is very typical for a high-mileage engine. De-carbonization or repair with replacement of piston rings, liners, valve stem seals, oil seals and other parts of the entire set will help.
- Oil leak. Occurs due to wear of the pressure sensor. You need to buy and install a new one.
- Oil pressure instability. The problem is with the sensor itself. The pressure needs to be measured and the sensor replaced.
- Change of turns. It is necessary to check the KXX valve, throttle valve and DPDZ. If you reinstall the last two, there is a chance that they will not be installed correctly.
Even on turbocharged engine modifications, turbochargers do not differ in their long service life. They need to be changed after one hundred thousand kilometers. Also installed is not a very good drive for the oil pump. In general, an engine requires good oil. On modifications of “Beams”, when the timing belt breaks, the valves bend. In general, the motors are good, but time makes itself felt – even the latest FE-models are already quite old and worn out.
