Disadvantages of the Great Wall GW4D20B engine
The primary issue with this diesel engine is the gasket’s frequent failure as a result of overheating;
Any contaminants in diesel fuel cause CR Delphi fuel injectors to deteriorate rapidly;
Many complaints regarding lubricant consumption can be found on specialized forums;
Keep an eye on the timing belt’s condition because it serves little purpose and bends the valves when it breaks.
A short-lived water pump and turbocharger are among the motor’s shortcomings.
