Whenever you are alert of unusual symptoms on your vehicle, you are right to be intrigued, because a car represents a big annual budget and surprising malfunctions don’t lower the costs. So what if you feel like you have a leaking injector on your Genesis G80? You almost certainly figured it out thanks to black/oily drips along your engine motor, or a disturbed idle, or abnormal black smoke. These three symptoms are the main indicators of a leaking injector. As this problem can lead to more significant engine trouble on your car, we decided to prepare this article content to help you confirm the failure of a leaking injector and treat it correctly. To accomplish this, we will first of all look at the circumstance of gasoline injectors and then at those of diesel injectors Genesis G80.

Leaking injector on my petrol Genesis G80

It is crucial to know that the injectors on petrol and diesel engines are distinct, the truth is, the difference in combustion between these two types of engines makes the injection distinct. The key difference lies in the pressure undergone 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 Genesis G80: The different leaks

It should be noted that injector leaks on a Genesis G80 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 types of leaks:

  • Leakage from the top of the injector:
    It is plausible that you have a leak from the top of the injector, this is the component that is attached to the fuel rail, an O-ring will be involved in this.
  • Leak injector of the lower part:
    At last, you may experience a leak coming from the lower part of the injector of your car, this one will come from the junction with the engine and not with the rail as seen sooner.

Leaking injector on my diesel Genesis G80

Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure generates 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 Genesis G80: The different leaks

In the circumstance of leaking diesel injectors on your Genesis G80, there are three different types of leaks:

  • Leakage from the injector inlet:
    In cases like this, it is an inlet pipe that will deform along with time, commonly the leak will be at the clamping point.
  • Injector return leakage:
    As its name indicates, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Genesis G80 will be caused by 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 feel an air noise and a compression loss.

Leaking injector on my Genesis G80, how to fix the leak

And at last, we’re going to look at how to fix a leaking injector on your car. Frequently a leak is linked, as we have seen prior to this, to a worn seal as a result of the pressures suffered. But think that the pressure in the circuit is monumental, especially on diesel engines. So you will have to take some precautions:

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

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

  • Discover the source of the leak
  • Take apart the injector in question
  • Replace the corresponding seal kit
  • Reassemble the set up and tighten with a torque wrench in respect with the manufacturer’s standards.

In all situations, these interventions are not automatically very hard, but if you have the smallest hesitation in the treatment of your injector that leaks on your Genesis G80, we suggest you to get closer to your motor mechanic to avoid any bad handling that could severely harm the condition of your Genesis G80.
