Engine Overview and Common Failures
The weight of the 1JZ-GTE engine according to the catalog is 260 kg. The engine number 1JZ-GTE is located at the junction of the block with the oil pan. The overheating of the sixth cylinder is due to a design flaw, which leads the owner to modify the unit. Special kits are produced for this purpose. The turbine impeller can break. Some versions of this unit have a turbine with a ceramic impeller, which can break at any mileage and damage your engine with its fragments. The tensioner for the accessory belt is different from the old inline sixes. Here, all accessory units are hung on one belt with one tensioner, and it does not tolerate driving in an aggressive style, with accelerations and decelerations. The VVT-i system has a low lifespan. The VVT-i phase regulator, introduced in 1996, does not have a very long life. Even before reaching 100,000 km, it may leak or crack and require replacement. Minor breakdowns can occur. The weak points of this engine include an unreliable timing belt tensioner bracket, lack of hydraulic compensators, as well as frequent leaks in the pump and camshaft seals.
