Problems:

Oil leaks
The Toyota 3UZ-FE engine, found in the 2004 Lexus LS, is known to develop oil leaks over time, particularly from the valve cover gaskets and camshaft seals.
Timing belt wear
The 3UZ-FE engine uses a timing belt, which should be replaced at regular intervals to avoid potential engine damage. If not maintained, the timing belt can wear out and potentially break, causing significant engine issues.
Ignition coil failure
This engine can experience ignition coil failures, which can lead to misfires, rough idling, and reduced engine performance.
Cooling system issues
Over time, components of the cooling system such as the radiator, water pump, and hoses may fail, leading to overheating problems.
Carbon build-up
The V-shaped 8-cylinder configuration can be prone to carbon build-up on the intake valves and combustion chamber, which can affect engine performance and fuel economy.
Throttle body problems
The throttle body can become dirty or malfunction, causing poor throttle response and erratic engine behavior.
Mass air flow sensor (maf) issues
The MAF sensor can become dirty or fail, leading to incorrect air-fuel mixture readings and resulting in poor engine performance and fuel economy.
Oxygen sensor failure
Faulty oxygen sensors can cause the engine to run inefficiently, increasing fuel consumption and emissions.

The V-shaped 8-cylinder configuration can be prone to carbon build-up on the intake valves and combustion chamber, which can affect engine performance and fuel economy.
Throttle body problems
The throttle body can become dirty or malfunction, causing poor throttle response and erratic engine behavior.
Mass air flow sensor (maf) issues
The MAF sensor can become dirty or fail, leading to incorrect air-fuel mixture readings and resulting in poor engine performance and fuel economy.
Oxygen sensor failure
Faulty oxygen sensors can cause the engine to run inefficiently, increasing fuel consumption and emissions.
