Most common problems:

Oil leaks

The 1UZ-FE engine, particularly in older models like the 1992 Lexus SC, is prone to oil leaks, especially from the valve cover gaskets and camshaft seals.

Timing belt wear

The timing belt on the 1UZ-FE engine should be replaced at regular intervals (typically every 90,000 miles) to avoid failure, which can cause significant engine damage.

Cooling system issues

Older vehicles, including the 1992 Lexus SC, may experience cooling system problems such as radiator leaks, water pump failure, or thermostat issues.

Ignition system problems

The ignition coils and spark plugs may wear out over time, leading to misfires and reduced engine performance.

Vacuum leaks

Vacuum hoses and intake manifold gaskets can deteriorate with age, causing rough idling, poor fuel economy, and engine performance issues.

Fuel injector problems

Dirty or failing fuel injectors can cause uneven fuel delivery, leading to poor engine performance and reduced fuel efficiency.

Exhaust manifold cracks

The exhaust manifolds on the 1UZ-FE engine can develop cracks over time, causing exhaust leaks and potentially impacting engine performance.

Mass air flow (maf) sensor failure

A failing MAF sensor can lead to incorrect air/fuel mixture readings, resulting in poor engine performance and fuel economy.
