Injectors, removing and installing: Notes
NOTE:
Faulty injectors can cause the following malfunctions:
- Engine runs rough
- Diesel knock
- Knocking in one or more cylinders
- Engine overheating
- Loss of power
- Excessive black smoke
- Increased fuel consumption
- Excessive blue smoke when starting from cold
Faulty injectors can be located by loosening the high pressure line union on each injector in turn, with the engine running at a fast idling speed. If the engine speed remains constant after loosening a line union, this indicates a faulty injector.
