The 2001 Toyota Tundra with the 2UZ-FE engine is known for oil sludge buildup, which can occur if oil changes are not performed regularly. This can lead to engine damage and reduced performance.

The 2UZ-FE engine uses a timing belt, which needs regular replacement. If the timing belt fails, it can cause severe engine damage, as the engine is an interference design.

Owners have reported issues with cracked exhaust manifolds, which can lead to exhaust leaks and increased engine noise.

The 2UZ-FE engine can experience problems with carbon buildup on spark plugs, which can cause misfires and reduced fuel efficiency.

The ignition coils on these engines can fail over time, leading to misfires and rough engine performance.

Some users have reported issues with rough idling or stalling during cold starts, often related to fuel system or ignition components.

The 2UZ-FE engine in the 2002 Toyota Tundra is known for developing oil leaks, particularly from the valve cover gaskets and oil pan gaskets.

The 2UZ-FE engine uses a timing belt, which requires periodic replacement. If not replaced on schedule, the belt can wear out and potentially lead to severe engine damage.

Problems with the radiator, water pump, or thermostat can cause overheating, which can be detrimental to the engine's performance and longevity.

The exhaust manifolds on V-shaped engines like the 2UZ-FE can crack over time, leading to exhaust leaks and reduced engine efficiency.

The 2UZ-FE engine can experience issues with spark plugs and ignition coils, leading to misfires and rough running conditions.

Over time, carbon deposits can build up in the intake manifold and on the intake valves, affecting engine performance and fuel efficiency.

The throttle body can become dirty or malfunction, leading to poor throttle response and erratic idling.

Clogged or failing fuel injectors can lead to poor engine performance, reduced fuel economy, and increased emissions.

Various engine sensors, such as the mass air flow sensor, oxygen sensors, and camshaft position sensor, can fail, causing the engine to run poorly or trigger the check engine light.

The 2UZ-FE engine can suffer from oil sludge buildup if oil changes are not performed regularly, leading to poor engine performance and potential damage.

The timing belt on this engine needs regular replacement according to the manufacturer's schedule, as failure can result in severe engine damage.

Over time, fuel injectors can become clogged or fail, leading to poor fuel economy, misfires, or rough idling.

This engine may experience issues with the cooling system, such as radiator leaks or water pump failures, which can lead to overheating.

The exhaust manifolds on this engine are prone to developing cracks, leading to exhaust leaks and possible engine performance issues.

Spark plugs may wear out or become fouled, causing engine misfires, reduced fuel efficiency, and rough running.

The throttle body can become dirty or malfunction, leading to poor engine response and idle issues.

Over time, vacuum hoses and connections can degrade, causing leaks that affect engine performance and fuel efficiency.

The camshaft position sensor can fail, resulting in engine stalling, misfires, or difficulty starting.

The knock sensor may fail, leading to a loss of power and poor engine performance due to improper ignition timing adjustments.

The 2UZ-FE engine is known for oil sludge buildup, which can clog oil passages and cause engine damage if not addressed.

The 2UZ-FE engine uses a timing belt that requires regular replacement. If the timing belt wears out or breaks, it can cause severe engine damage.

This engine is prone to developing cracks in the exhaust manifold, which can lead to exhaust leaks and reduced engine performance.

Over time, the valve cover gaskets can degrade and cause oil leaks, which can lead to engine misfires and other issues if not repaired.

The Tundra's cooling system can develop leaks or fail, leading to engine overheating and potential head gasket failure.

The mass air flow (MAF) sensor can fail over time, leading to poor engine performance, stalling, and reduced fuel efficiency.

Carbon buildup in the throttle body can cause rough idling, poor acceleration, and engine stalling.

Clogged or failing fuel injectors can lead to poor engine performance, misfires, and reduced fuel economy.

The 2UZ-FE engine can experience knock sensor failures, which can result in the engine running poorly and reduced overall performance.

Common in the 2UZ-FE engine, often due to valve cover gasket wear or oil pan gasket issues.

The 2UZ-FE engine uses a timing belt that requires regular replacement (usually every 90,000 miles) to prevent catastrophic engine damage.

The V-shaped configuration can cause stress on the exhaust manifolds, leading to cracks and exhaust leaks.

2UZ-FE engines are known for ignition coil problems, which can cause misfires and poor engine performance.

Carbon buildup in the throttle body can affect engine performance and lead to rough idling or stalling.

Radiator and water pump failures are common, which can lead to overheating if not addressed promptly.

Clogged or faulty fuel injectors can cause rough running or poor fuel economy.

Faulty oxygen sensors can lead to poor fuel economy and increased emissions.

A dirty or failing MAF sensor can cause erratic engine behavior and reduced performance.
