OK so we've got:-

1) Sticking piston rings
2) Injection pumps (may be)



Any valve wear - like the leaded / unleaded petrol problem?

Please continue to add to this list!


On a slightly different subject:- Does anyone know where to find specific fluid properties of Diesel. Such as viscosity within certain temperature limits / permitted water content / filtration limits etc etc.
