The 3UR-FE engine in the Toyota Sequoia is known to develop oil leaks, particularly from the valve cover gaskets and timing cover, which can lead to reduced engine performance and potential damage if not addressed.

Some 2014 Toyota Sequoia models with the 3UR-FE engine may experience a rattling noise from the timing chain tensioner, especially upon startup, which can indicate wear and the need for replacement to avoid potential engine damage.

The V-shaped configuration in this engine can lead to increased heat and stress on the exhaust manifolds, causing them to crack and result in exhaust leaks and increased engine noise.

The direct injection system in the 3UR-FE engine may lead to carbon buildup on the intake valves over time, which can cause rough idling, reduced fuel efficiency, and performance issues.

The engine may experience problems with the cooling system, such as radiator leaks or a failing water pump, which can lead to overheating if not promptly repaired.

The V8 configuration in the 3UR-FE engine can develop oil leaks over time, particularly around the valve covers and oil pan gaskets. This can lead to oil loss and potential engine damage if not addressed.

The 3UR-FE engine uses a timing chain, which can wear out over time, causing rattling noises and potential timing issues. If the chain stretches too much, it can affect engine performance and may require replacement.

The PORT injection system in the 3UR-FE engine can sometimes develop issues with fuel injectors becoming clogged or failing, leading to rough idling, misfires, and decreased fuel efficiency.

V8 engines with port injection can suffer from carbon buildup on the intake valves and ports, affecting performance and fuel economy. Regular maintenance and cleaning are required to mitigate this issue.

Over time, the cooling system components such as the radiator, water pump, and thermostat can wear out or fail, leading to overheating issues. This is particularly important in a high-performance engine like the 3UR-FE.

The higher horsepower output of the 3UR-FE engine can cause spark plugs to wear out more quickly, leading to misfires and reduced engine performance. Regular inspection and replacement are necessary to maintain optimal function.

The V-shaped configuration can put extra stress on the exhaust manifolds, potentially leading to cracks or leaks, which can cause ticking noises and reduce engine efficiency.

The Toyota 3UR-FBE engine is known to experience higher-than-normal oil consumption. This can lead to low oil levels and potential engine damage if not monitored closely.

The V-shaped configuration of the engine can sometimes lead to oil leaks from the camshaft towers, which can result in oil pooling and potential damage to engine components.

Over time, the timing chain in the 3UR-FBE engine may experience wear, leading to engine performance issues and potentially costly repairs if the chain fails.

The port fuel injection system can sometimes cause issues with fuel injectors becoming clogged or failing, leading to poor engine performance and reduced fuel efficiency.

The cooling system in this engine can be prone to failures, such as water pump leaks or radiator issues, which can cause the engine to overheat.

Due to the engine configuration and port fuel system, spark plugs may foul more frequently, leading to misfires and reduced engine performance.

The exhaust manifolds on this engine can sometimes develop cracks, leading to exhaust leaks and potentially triggering the check engine light.

Problems with the electronic throttle control system can lead to throttle response issues, including hesitation or surging during acceleration.

The V8 configuration in the 3UR-FE engine can develop oil leaks over time, particularly around the valve covers and oil pan gaskets. This can lead to oil loss and potential engine damage if not addressed.

The Toyota Tundra with a 3UR-FE V8 engine is known for developing oil leaks, particularly from the valve cover gaskets and the timing chain cover.

Over time, the timing chain tensioner can wear out or fail, leading to a rattling noise on startup and potential engine damage if not addressed.

The exhaust manifolds on this engine can crack or warp, causing exhaust leaks that can lead to a ticking noise and reduced engine performance.

The fuel injectors may become clogged or fail, causing rough idling, poor fuel economy, and misfires.

The spark plugs can wear out prematurely, leading to misfires, reduced fuel efficiency, and difficulty starting the engine.

Radiator and water pump failures are not uncommon, which can lead to overheating and potential engine damage.

Carbon can build up in the throttle body, causing rough idling, hesitation, and reduced throttle response.

The knock sensors on this engine can fail, causing the engine to run improperly and potentially leading to engine damage if not replaced.

The camshaft towers can develop oil leaks, which can cause oil to drip onto the exhaust manifold and create a burning smell.
