Problems:

Oil leaks
The 1UZ-FE engine, especially in older vehicles, can develop oil leaks around the valve cover gaskets and rear main seal due to age and wear.
Timing belt issues
The timing belt in the 1UZ-FE engine needs regular replacement (typically every 90,000 miles). If neglected, it can lead to severe engine damage.
Overheating
Older engines can suffer from overheating due to clogged radiators, failing water pumps, or malfunctioning thermostats.
Ignition system problems
The ignition coils and spark plugs may wear out over time, leading to misfires and rough engine performance.
Fuel injector problems
Clogged or failing fuel injectors can lead to poor fuel economy and engine performance issues.
Sensor failures
Oxygen sensors and other engine management sensors can fail, leading to poor engine performance and increased emissions.
Head gasket failure
Although not extremely common, head gasket issues can occur, leading to coolant leaks and overheating problems.
Intake manifold gasket leaks
The gasket can deteriorate over time, causing vacuum leaks and poor engine performance.
