In cases where you are aware of unusual signs on your automobile, you are right to be concerned, because a car represents a massive annual budget and unforeseen breakdowns don’t reduce the expenses. So what if you find that you have a leaking injector on your Dacia Lodgy? You likely figured it out thanks to black/oily drips along your engine, or a disturbed idle, or abnormal black smoke. These three signs of illness are the main symptoms of a leaking injector. As this troubles can bring on more serious engine problems on your car, we made a decision to compose this content to help you confirm the failure of a leaking injector and deal with it properly. To do so, we will initially look into the case of gasoline injectors and then at those of diesel injectors Dacia Lodgy.

Leaking injector on my petrol Dacia Lodgy

It is important to know that the injectors on petrol and diesel engines are distinct, actually, 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 Dacia Lodgy: The different leaks

It should be said that injector leaks on a Dacia Lodgy equipped with a petrol engine are pretty rare. This is because of 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 portion 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 suffer a leak coming from the lower part of the injector of your car, this one will occur from the junction with the engine and not with the rail as seen previously.

Leaking injector on my diesel Dacia Lodgy

Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system 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 Dacia Lodgy: The different leaks

In the case of leaking diesel injectors on your Dacia Lodgy, there are three several types of leaks:

  • Leakage from the injector inlet:
    In this case, it is an inlet pipe that will deform with time, commonly 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 Dacia Lodgy 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 annoying, 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 checking you have oil leaking but it does not come from your injectors, we recommend you to read this content on the existence of oil leaking on your Dacia Lodgy.

Leaking injector on my Dacia Lodgy, how to fix the leak

And to finish, we’re going to look into how to fix a leaking injector on your car. Oftentimes a leak is linked, as we have seen sooner, 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 safety measures:

  • Lower the pressure before any work is carried out…
  • Covering 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 frequently be restricted to swapping the seals that have failed:

  • Find the source of the leak
  • Take apart the injector in question
  • Change the corresponding seal kit
  • Reassemble the assembly and tighten with a torque wrench in accordance with the manufacturer’s standards.

In all cases, these interventions are not inevitably complicated, but if you have the slightest doubt in the treatment of your injector that leaks on your Dacia Lodgy, we recommend you to get closer to your auto technician to avoid any bad manipulation that could critically harm the condition of your Dacia Lodgy.
