Spec:

Engine Model

L77

Engine Number of Cylinders

Other Engine Info

Book code: BE. AFM (Active Fuel Management), Aluminum Engine

Problems:

Oil consumption

The L77 engine is known to have issues with high oil consumption due to its Active Fuel Management (AFM) system.

Lifter failure

The AFM system can lead to premature lifter failure, causing ticking noises and potential engine misfires.

Timing chain wear

This engine can experience timing chain wear, which may result in poor engine performance and potential engine damage if not addressed.

Valve cover leaks

The aluminum construction can lead to valve cover gasket leaks, causing oil seepage and potential engine compartment mess.

Coolant leaks

The engine may develop coolant leaks from the water pump or other cooling system components, leading to overheating issues.

The 2015 Chevrolet Caprice Police Vehicle is a robust, 4-door sedan powered by a 6.0L V8 engine with flexible fuel capability. Built in Elizabeth, South Australia by Holden under General Motors, it features comprehensive safety measures including multiple airbags and a direct TPMS. Ideal for law enforcement, it combines power with advanced safety features.

Spec:

Engine Model

L77

Engine Number of Cylinders

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.
