Disadvantages of the Z19DT engine
This engine is straightforward and dependable because it lacks troublesome swirl flaps;
The metering valve is the Bosch Common Rail fuel system’s weak point; nozzles frequently start to pour at high mileage, but these are typically fixed;
Here, the turbine serves as a resource; however, the exhaust manifold may crack or distort around the fourth cylinder, and the geometry of the blades changes from coke to wedge.
