Disadvantages of the EP6DTS engine
The direct injection system’s injection pump, which has a 50,000 km resource, is the engine’s weak point;
The timing chain has very little use and occasionally needs to be adjusted every 30,000 kilometers;
The engine’s oil burner, intake pipe coking, and oil supply pipes are also well-known;
A vacuum pump wedge is frequently present, occasionally even with the camshaft being cranked;
Additionally, engine owners frequently replace the water pump, thermostat, and lambda probes.
