Disadvantages of the Z19DT engine
- This is a simple and reliable engine, as it does not have problematic swirl flaps;
- The weak point of the Bosch Common Rail fuel system is the metering valve;
- At high mileage, nozzles often begin to pour, but usually they are repaired;
- The turbine is resource here, except that the blades of geometry change coke and wedge;
- The exhaust manifold may crack or deform around the 4th cylinder.
