If you are alert of abnormal symptoms on your car, you are right to be intrigued, because a car represents a huge annual budget and surprising breakdowns don’t reduce the costs. So what if you find that you have a leaking injector on your Citroen C3 Pluriel? You most likely figured it out thanks to black/oily drips along your engine unit, or a disturbed idle, or unusual black smoke. These three manifestations are the main symptoms of a leaking injector. As this problem can cause more significant engine concerns on your car, we thought we would produce this content page to help you ensure the failure of a leaking injector and deal with it properly. To achieve this, we will initially look into the circumstance of gasoline injectors and then at those of diesel injectors Citroen C3 Pluriel.

Leaking injector on my petrol Citroen C3 Pluriel

It is essential to know that the injectors on petrol and diesel engines are distinct, in fact, the difference in combustion between these two types of engines makes the injection distinct. The biggest 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 Citroen C3 Pluriel: The different leaks

It should be mentioned that injector leaks on a Citroen C3 Pluriel equipped with a petrol engine are pretty rare. This is caused by 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 linked to the fuel rail, an O-ring will be involved in this.
  • Leak injector of the lower part:
    Finally, you may encounter a leak coming from the lower portion 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 Citroen C3 Pluriel

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 Citroen C3 Pluriel: The different leaks

In the circumstance of leaking diesel injectors on your Citroen C3 Pluriel, there are three several types of leaks:

  • Leakage from the injector inlet:
    In this case, it is an inlet pipe that will deform along with time, usually the leak will be at the clamping point.
  • Injector return leakage:
    As its name implies, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Citroen C3 Pluriel 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 examining you have oil leaking but it does not come from your injectors, we suggest you to read this content page on the existence of oil leaking on your Citroen C3 Pluriel.

Leaking injector on my Citroen C3 Pluriel, how to fix the leak

And to finish, we’re going to look into how to fix a leaking injector on your car. Very often a leak is associated, as we have seen sooner, to a worn seal due to the pressures endured. But think that the pressure in the circuit is tremendous, specifically 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.

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

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

In all cases, these interventions are not specifically complex, but if you have the slightest uncertainty in the treatment of your injector that leaks on your Citroen C3 Pluriel, we suggest you to get closer to your auto mechanic to avoid any bad handling that could seriously harm the condition of your Citroen C3 Pluriel.
