Other Engine Info
Book code: BE. AFM (Active Fuel Management), Aluminum Engine
Problems:
Oil consumption
The L77 engine is known for excessive oil consumption, which could be due to issues with the Active Fuel Management (AFM) system and piston rings.
Lifter failure
The AFM system can cause premature wear on the lifters, leading to lifter failure and potentially more severe engine issues.
Timing chain wear
This engine may experience timing chain wear, which can lead to poor engine performance and potentially catastrophic failure if not addressed.
Carbon build-up
Engines with AFM technology, like the L77, can suffer from carbon build-up on the intake valves, leading to rough idling and reduced performance.
Oil pump issues
Some L77 engines experience problems with the oil pump, which can lead to low oil pressure and engine damage if not corrected.
Overheating
The aluminum construction of the L77 engine can make it prone to overheating if the cooling system is not properly maintained.
Valve guide wear
Premature valve guide wear can lead to increased oil consumption and engine performance issues.
Sensor failures
Various sensors (e.g., oxygen sensors, MAF sensors) can fail, leading to incorrect engine management and reduced performance.
