In the event you are aware of unusual signs on your car, you are right to be worried, because a car represents a big annual budget and sudden malfunctions don’t reduce the expenses. So what if you think that you have a leaking injector on your Land Rover Range Rover? You most likely figured it out thanks to black/oily drips along your engine motor, or a disturbed idle, or unconventional black smoke. These three signs of illness are the main symptoms of a leaking injector. As this problem can lead to more severe engine problems on your car, we made a decision to write this content to help you confirm the failure of a leaking injector and deal with it properly. To achieve this, we will first check out the case of gasoline injectors and then at those of diesel injectors Land Rover Range Rover.

Leaking injector on my petrol Land Rover Range Rover

It is crucial to know that the injectors on petrol and diesel engines are distinct, actually, the difference in combustion between these two sort of engines makes the injection distinct. The main difference lies in the pressure experienced by the injectors, on a petrol engine it will vary between 3.5 bars for indirect injection and 120 bars for indirect injection.

Leaking injector on a petrol Land Rover Range Rover: The different leaks

It should be mentioned that injector leaks on a Land Rover Range Rover equipped with a petrol engine are pretty rare. This is due to the much lower pressure in the petrol intake systems. Even so, there are two sort of leaks:

  • Leakage from the top of the injector:
    It is possible that you have a leak from the top of the injector, this is the part that is linked to the fuel rail, an O-ring will be involved in this.
  • Leak injector of the lower part:
    Finally, you may suffer a leak coming from the lower portion of the injector of your car, this one will appear from the junction with the engine and not with the rail as seen before.

Leaking injector on my diesel Land Rover Range Rover

Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure creates very high pressure in the engine, as do the injectors. On these models, the pressure is more than 10 times higher than on the direct injection of car petrol engines, reaching 1800 to 2000 bars.

Leaking injector on diesel Land Rover Range Rover: The different leaks

In the case of leaking diesel injectors on your Land Rover Range Rover, there are three several sort of leaks:

  • Leakage from the injector inlet:
    In this instance, it is an inlet pipe that will deform as time passes, generally the leak will be at the clamping point.
  • Injector return leakage:
    As its name reveals, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Land Rover Range Rover will be a consequence of an O-ring or its plastic tip that leaks.
  • Injector base leak:
    This injection leak is one of the most troublesome, it is the junction between the engine and the injector nose that leaks at a copper seal, you should find an air noise and a compression loss.
  • If after verifying you have oil leaking but it does not come from your injectors, we advise you to consult this content on the presence of oil leaking on your Land Rover Range Rover.

Leaking injector on my Land Rover Range Rover, how to fix the leak

And at last, we’re going to check out how to fix a leaking injector on your car. Frequently a leak is linked, as we have seen previously, to a worn seal due to the pressures suffered. But think that the pressure in the circuit is gigantic, especially on diesel engines. So you will have to take some measures:

  • Lower the pressure before any work is completed…
  • Masking you to avoid the risk of fuel spillage
  • NEVER work on a running diesel engine injector.

Concerning the repair part of your leak, it will very often be limited to swapping the seals that have failed:

  • Locate the source of the leak
  • Dismantle the injector in question
  • Change the corresponding seal kit
  • Reassemble the assembly and tighten with a torque wrench in respect with the manufacturer’s standards.

In all cases, these interventions are not inevitably complex, but if you have the tiniest doubt in the treatment of your injector that leaks on your Land Rover Range Rover, we advise you to get closer to your auto technician to avoid any bad manipulation that could critically harm the condition of your Land Rover Range Rover.
