Other Engine Info
Engine Type: PORT+DIRECT
Problems:
Oil consumption
The 2GR-FSE engine is known for higher-than-average oil consumption, which can lead to low oil levels if not monitored regularly.
Carbon build-up
Due to the direct injection system, carbon deposits can accumulate on the intake valves, affecting performance and fuel efficiency.
Water pump failure
The water pump on this engine has been reported to fail prematurely, which can lead to overheating if not addressed.
Timing chain tensioner issues
The timing chain tensioner can wear out over time, leading to a noisy engine or even potential timing chain failure.
Fuel injector problems
The dual injection system (port and direct) can have issues with fuel injectors, potentially causing misfires or rough idling.
Pcv valve failure
The Positive Crankcase Ventilation (PCV) valve can fail, leading to increased oil consumption and potential engine performance issues.
Cooling system leaks
There have been reports of leaks in the cooling system, particularly around the radiator and hoses, which can lead to overheating.
Intake manifold gasket leaks
The intake manifold gasket can deteriorate, causing vacuum leaks that affect engine performance and fuel economy.
Knock sensor failure
The knock sensor can fail, causing the engine control unit (ECU) to misinterpret engine knocking and potentially retard timing excessively.
