Disadvantages of the A24XE engine
The timing chain drive with an unpredictable resource is the primary cause of these issues.
The front cover will also be added to the parts list if the chain is not changed in a timely manner.
Phase regulator malfunctions are frequently the cause of the engine’s unstable operation.
Increased oil consumption from the first kilometers is a complaint made by some owners.
Because the engine metal is so soft, make sure you use a torque wrench.
