Manufactured by General Motors in Australia, this model is designed to meet the demanding needs of law enforcement.

Spec:

Engine Model
L77
Engine Number of Cylinders
8
Other Engine Info
ALUM, AFM: Active Fuel Management

Problems:

Oil consumption
The L77 engines, especially those with Active Fuel Management (AFM), are known to consume oil at an accelerated rate due to issues with the AFM system.
Afm lifters failure
The AFM system can cause lifters to collapse, leading to misfires or engine noise, which may necessitate lifter replacement.
Timing chain wear
Over time, the timing chain can stretch, leading to poor engine performance and potentially causing the engine to run out of time.
Intake manifold gasket leaks
This engine may develop leaks at the intake manifold gaskets, leading to vacuum leaks and poor engine performance.
Spark plug fouling
Due to oil consumption and combustion issues, spark plugs can foul more frequently, causing misfires and reduced engine performance.
Carbon buildup
Direct injection engines like the L77 can experience carbon buildup on the intake valves, affecting engine efficiency and performance.
Transmission issues
While not directly related to the engine, the associated transmission in the Caprice Police Vehicle can experience issues due to the high-stress usage typical of police vehicles.
Coolant leaks
The engine may develop coolant leaks, often around the water pump or radiator, leading to overheating issues if not addressed promptly.
