DIESEL ENGINE
Norsk
1

The car gives gas by itself, especially when idling.

This is probably due to a diaphragm in the maximum quantity regulator in the diesel pump having ruptured. Diesel then enters the air hose that goes to the air manifold.

2

The engine stalls while driving, or misfires, or won't start.

This may be due to a fault in the stop valve on the diesel pump.

3

The engine runs unevenly.

This may be due to air getting into the diesel. Put on transparent hoses before the filter, and between the filter and the pump (and possibly the pre-heater, if it is connected). Bleed the filter and pump, start the engine and see if there are air bubbles in any of the hoses. (Do not drive with the transparent hoses.)

4

The engine loses power when you give it a lot of gas, and large amounts of brown-black smoke also come from the exhaust.

You probably need a new air filter.

Diesel is leaking from the back (toward the torpedo wall) of the diesel pump.

Both diaphragms on the maximum flow regulator have probably ruptured.

Diesel is leaking at the right front wheel.

The leak is probably coming from the diesel pump's seal ring.

The engine stops and will not start again.

This may be because the timing belt has broken.

8

There are "clicking" noises from the engine.

This may be due to the valves needing adjustment.

9

The car consumes a lot of coolant, and there is a grey-white coating on the underside of the oil filler cap.

The coolant enters the oil; you probably need to replace the head gasket.

The engine boils.

You probably have too little coolant.

Problematic gas pedal.

It may be that the sound insulation under the hood has come loose, causing problems for the throttle lever on the diesel pump.
