Disadvantages of the EP6CDTM engine
The direct injection system, particularly the injection pump, is responsible for the majority of these issues.
An unreliable timing chain, which typically has a resource of less than 100,000 km, comes in second.
These engines are also well-known for their oil burn and intake and supply pipe coking.
This engine’s turbine fails very quickly due to a lack of lubrication.
The thermostat, water pump, and oil pump are additional motor weak points.
