Disadvantages of the N47D20 engine
- The most famous problem of the motor in stretching the timing chain on runs up to 100,000 km;
- Replacing the timing kit is done only with the removal of the engine and is not cheap;
- Swirl flaps in the intake manifold quickly overgrow with soot and jam;
- The crankshaft damper has a modest resource and may require replacement by 100,000 km;
- Prolonged overheating of a diesel engine often leads to cracks between the cylinders.
Some of the provided points here are not really true.
> The most famous problem of the motor in stretching the timing chain on runs up to 100,000 km
Here should be said which exact specification it is related to:
for the specifications of the first revision (Mostly E series, i.e. N47D20T0) the “normal” safe milage is about 180k km. On the second revision, (i.e. N47D20T1 – mostly F series) timing chains mechanism has been revised. So here normally engines could run 200-250k and have no signs of stretched timing chains.
However, on the engine N20, there is the problem with timing chains on 80-100k km, but the root cause there are plastic chain dampers.
