Problems:

Turbocharger failure
The 2JZ-GTE engine is equipped with a twin-turbo setup, and over time, the turbos can wear out or fail, leading to reduced engine performance and increased exhaust smoke.
Head gasket issues
Due to the high-performance nature of the engine, especially when modified, head gasket failures can occur, leading to coolant leaks and overheating problems.
Oil leaks
Common oil leak points on the 2JZ-GTE include the valve cover gasket, front main seal, and rear main seal, which can lead to oil loss and potential engine damage if not addressed.
Ignition coil failure
The ignition coils on the 2JZ-GTE may fail over time, leading to misfires, rough idling, and reduced power output.
Fuel system problems
Issues with the fuel injectors or fuel pump can lead to poor fuel delivery, resulting in performance loss, stalling, or difficulty starting the engine.
Timing belt wear
The timing belt needs regular replacement to prevent it from snapping, which could cause significant engine damage due to the interference engine design.

Problems:

Oil consumption
The 2JZ-GE engine can sometimes consume oil at higher mileage, which may require more frequent topping off or oil changes.
Head gasket failure
Over time, the head gasket can fail, leading to coolant leaks and potential engine overheating.
Valve stem seal wear
Valve stem seals can wear out, causing oil to leak into the combustion chamber and resulting in blue smoke from the exhaust.
Camshaft wear
The camshaft may wear down over time, affecting engine performance and necessitating replacement.
Fuel injector issues
Fuel injectors can become clogged or fail, leading to poor engine performance and reduced fuel efficiency.
Timing belt wear
The timing belt should be replaced at regular intervals to prevent it from snapping, which can cause severe engine damage.
Ignition coil failure
Ignition coils can fail, causing misfires and poor engine performance.
Oxygen sensor failure
The oxygen sensor can fail, leading to incorrect air-fuel mixture readings and reduced fuel efficiency.
Intake manifold gasket leaks
The intake manifold gasket can deteriorate, causing vacuum leaks and rough idling.
Crankshaft position sensor failure
A failing crankshaft position sensor can lead to engine stalling or difficulty starting.
