Problems:

Oil leaks
The 1UZ-FE engine, especially in higher mileage vehicles, is known to develop oil leaks from the valve cover gaskets and the front main seal.
Timing belt wear
The 1UZ-FE engine uses a timing belt that requires periodic replacement. If not replaced, it can lead to catastrophic engine damage.
Cooling system issues
Older engines like the 1UZ-FE can suffer from radiator, water pump, and thermostat failures, leading to overheating problems.
Ignition coil failure
The ignition coils on this engine may fail over time, causing misfires and rough running conditions.
Power steering pump leaks
The power steering pump in the 1UZ-FE is prone to developing leaks, leading to loss of power steering fluid and functionality.
Carbon build-up
Over time, carbon deposits can accumulate in the intake manifold and on the valves, affecting performance and fuel efficiency.
Sensor malfunctions
The age of the vehicle can lead to various sensor issues, such as the oxygen sensor, mass air flow sensor, and throttle position sensor, causing performance problems and check engine lights.
Exhaust manifold cracks
The exhaust manifold on the 1UZ-FE can develop cracks, leading to exhaust leaks and increased engine noise.
Vacuum leaks
The rubber vacuum hoses can deteriorate over time, causing vacuum leaks that affect engine performance and idle quality.
Fuel injector issues

Problems:

Overheating
The 2JZ-GE engine is known to overheat if the cooling system is not properly maintained. This can be due to a faulty radiator, water pump, or thermostat.
Oil leaks
Older engines like the 2JZ-GE can develop oil leaks, often from the valve cover gaskets or oil pan gaskets, which can lead to low oil levels and engine damage if not addressed.
Faulty ignition coils
The ignition coils in the 2JZ-GE can fail over time, leading to misfires, rough idling, and poor engine performance.
Timing belt wear
The 2JZ-GE uses a timing belt that needs to be replaced at regular intervals. Failure to replace the timing belt can result in it breaking and causing severe engine damage.
Vacuum leaks
The engine’s vacuum lines can become brittle and crack over time, leading to vacuum leaks that result in poor engine performance and fuel economy.
Sensor failures
Sensors such as the oxygen sensor, mass air flow sensor, and crankshaft position sensor can fail, causing the engine to run poorly or not start at all.
Head gasket failure
With age and high mileage, the head gasket can fail, leading to coolant leaks, oil contamination, and overheating issues.
LEXUS GS 1993

The 1993 Lexus GS 300, manufactured by Toyota Motor Corporation at the Tahara Plant in Japan, features a 3.0L 2JZ-GE inline-six engine producing 220-227 hp.
