Engine Overview and Common Failures
The weight of the 2JZ-GTE engine according to the catalog is 270 kg. The engine number 2JZ-GTE is located at the joint of the block with the oil pan. The turbine impeller can break down. Some modifications of this engine were equipped with turbines with a ceramic impeller, which tends to disintegrate, and its crumbs immediately get into the combustion chamber. This happens at any mileage and it is better to replace it preventively with a metal one. Unlike the old inline engines, all auxiliary units here hang on one belt with one tensioner and it does not tolerate rough driving with accelerations and braking. The VVT-i system has a low resource. After the update in 1997, the engine received the VVT-i phase control system on the intake. Its reliability is not high and sometimes it starts to crack even before a mileage of 150 thousand km. Among minor issues, we can mention the low reliability of the pump and viscous coupling, weak timing belt tensioner bracket, as well as frequent leaks of camshaft seals. Since hydraulic compensators are not provided here, valve clearance needs to be adjusted.
