Problems:

Oil leak

The 2JZ-GE engine, like many older engines, can develop oil leaks over time, often from the valve cover gasket, oil pan, or front/rear main seals.

Idle issues

This can include rough idling or stalling, often due to a dirty or failing idle air control valve or throttle body issues.

Timing belt wear

The 2JZ-GE uses a timing belt which can wear out or break if not replaced at recommended intervals, leading to potential engine damage.

Cooling system problems

Issues such as radiator leaks or failing water pumps are common, which can lead to overheating if not addressed.

Sensor failures

Older engines like the 2JZ-GE can have issues with sensors such as the oxygen sensor, mass airflow sensor, or crankshaft position sensor failing over time.

Valve cover gasket leak

Common in higher mileage engines, leading to oil seepage.

Ignition coil failure

Can cause misfires or poor engine performance, requiring replacement.

Fuel injector issues

Clogged or failing fuel injectors can lead to poor engine performance and fuel economy.

3UZ-FE

Engine Number of Cylinders

Problems:

Oil leaks

The 3UZ-FE engine may develop oil leaks over time, particularly around the valve cover gaskets and camshaft seals.

Timing belt wear

The engine uses a timing belt that requires periodic replacement. If not replaced on schedule, it can wear out and potentially cause engine damage.

Cooling system issues

Older models like the 2001 Lexus GS may experience problems with the radiator, water pump, or thermostat, leading to overheating.

Ignition coil failure

The ignition coils on the 3UZ-FE engine can fail, leading to misfires and poor engine performance.

Carbon buildup

Over time, carbon can build up in the intake valves and combustion chambers, affecting engine efficiency and performance.

Fuel injector problems

The fuel injectors may get clogged or fail, causing poor fuel delivery and engine performance issues.

Sensor failures

Various engine sensors, such as the oxygen sensor or mass airflow sensor, can fail and lead to poor engine performance or increased emissions.

Vacuum leaks

Aging hoses and gaskets can develop leaks, causing the engine to run poorly or have idle issues.
