Problems:

Oil leaks
Common in older engines, oil leaks can develop around valve cover gaskets, oil pan gaskets, or the rear main seal.
Timing belt issues
The 3VZ-FE engine utilizes a timing belt, which needs regular replacement to avoid catastrophic engine damage if it fails.
Overheating
Due to age, components like the radiator, thermostat, or water pump might fail, leading to overheating issues.
Head gasket failure
The V-shaped 6-cylinder configuration can be prone to head gasket issues, especially in older vehicles.
Ignition system problems
Worn-out spark plugs, ignition wires, and distributor components can cause misfires and poor engine performance.
Vacuum leaks
Old vacuum hoses can crack and leak, leading to rough idling and poor engine performance.
Fuel system issues
Clogged fuel injectors or a failing fuel pump can cause poor fuel delivery and engine performance problems.
Carbon build-up
Over time, carbon deposits can accumulate on intake valves and combustion chambers, affecting engine efficiency and performance.
LEXUS ES 1990

The 1990 Lexus ES 250 is a classic executive sedan powered by a 2.5L V6 engine, producing 160 hp. Manufactured by Toyota, this 4-door saloon offers a comfortable ride with features like a driver-seat airbag and manual seat belts.

Problems:

Oil leaks
V-shaped engines like the 2VZ-FE are prone to oil leaks, especially around the valve cover gaskets and oil pan.
Timing belt wear
The 2VZ-FE engine uses a timing belt that requires regular replacement. Neglecting this can lead to severe engine damage.
Overheating
Due to age and potential issues with the cooling system, 1990 Lexus ES models can experience overheating, often related to radiator or thermostat failure.
Ignition coil failure
Older ignition systems, such as those in a 1990 model, can suffer from ignition coil failures, leading to misfires and poor engine performance.
Fuel injector problems
Over time, fuel injectors can become clogged or fail, which can lead to rough idling, poor fuel economy, and decreased performance.
Vacuum leaks
Vacuum hoses and gaskets can deteriorate over time, causing vacuum leaks that result in rough idling and stalling.
Transmission issues
The transmission (either 4A or 5M) linked to the engine may develop issues such as slipping, harsh shifts, or fluid leaks.
Sensor failures
Sensors like the oxygen sensor or the mass airflow sensor can fail, leading to poor engine performance and increased emissions.
LEXUS ES 1991

The 1991 Lexus ES 250 is a four-door sedan powered by a 2.5L V6 engine producing 160 horsepower. Manufactured by Toyota Motor Corporation in Toyota City, Japan, this executive sedan offers a choice between a 4-speed automatic or 5-speed manual transmission.

Can be due to a failing cooling system, such as a faulty radiator, water pump, or thermostat.
Timing belt issues
The timing belt may wear out or break, leading to engine misfires or complete engine failure.
Fuel injector problems
Clogged or malfunctioning fuel injectors can cause poor engine performance and lower fuel efficiency.
Ignition system failures
Worn spark plugs, bad ignition coils, or issues with the distributor can lead to misfires and starting problems.
Valve cover gasket leaks
Can cause oil to leak onto other engine parts, leading to potential damage and performance issues.
Exhaust manifold cracks
Can lead to exhaust leaks, reduced engine performance, and increased emissions.
Mass air flow sensor failure
Can cause incorrect air-fuel mixture, leading to rough idling, stalling, and poor fuel economy.
Egr valve blockage
Can cause increased emissions and reduced engine performance.
Crankshaft position sensor failure
Can cause stalling, misfires, and starting problems.
