Faulty injectors can cause severe detonation in the engine. In case of such a defect, you need to set the engine to idle speed and unscrew the union nuts of the inlet fuel lines in order. If after unscrewing such a nut the knocking in the engine disappears, then this indicates a faulty injector.
A faulty injector can also be found by alternately loosening the union nuts of the intake manifolds, and at higher idle engine speeds. If after unscrewing the nut the engine speed does not change, this indicates a faulty injector. The injector can be checked in a workshop using a pressure gauge.
The main signs of a faulty injector:
- misfire
- knocking in one or more cylinders
- engine overheating
- engine power loss
- too much black exhaust smoke
- high fuel consumption
Dismantling
Clean the fuel inlet lines with gasoline and remove them.
Remove the injectors.
Installation
(23-041) Use only new heat-insulating gaskets between the cylinder head and the injectors. The recess must face downwards, as shown in the figure.
Tighten the injectors to 70 Nm. Tighten the fuel inlet pipes to 25 Nm.
