In the event that you are informed of irregular signs on your automobile, you are right to be intrigued, because a car represents a huge annual budget and sudden breakdowns don’t lower the costs. So what if you feel as if you have a leaking injector on your Citroen C-crosser? You almost certainly figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or uncommon black smoke. These three symptoms are the main indicators of a leaking injector. As this problem can cause more severe engine problems on your car, we chose to write this content page to help you confirm the failure of a leaking injector and deal with it correctly. To achieve this, we will first of all check out the case of gasoline injectors and then at those of diesel injectors Citroen C-crosser.

Leaking injector on my petrol Citroen C-crosser

It is fundamental 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 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 Citroen C-crosser: The different leaks

It should be noted that injector leaks on a Citroen C-crosser equipped with a petrol engine are rather infrequent. This is as a result of the much lower pressure in the petrol intake systems. However, there are two sort of leaks:

  • Leakage from the top of the injector:
    It is conceivable that you have a leak from the top of the injector, this is the part that is connected to the fuel rail, an O-ring will be involved in this.
  • Leak injector of the lower part:
    At last, you may encounter 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 sooner.

Leaking injector on my diesel Citroen C-crosser

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 Citroen C-crosser: The different leaks

In the case of leaking diesel injectors on your Citroen C-crosser, there are three different sort of leaks:

  • Leakage from the injector inlet:
    In cases like this, it is an inlet pipe that will deform along with time, in most cases the leak will be at the clamping point.
  • Injector return leakage:
    As its name suggests, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Citroen C-crosser will be brought on 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 find an air noise and a compression loss.
  • If after examining you have oil leaking but it does not come from your injectors, we advise you to consult this content page on the presence of oil leaking on your Citroen C-crosser.

Leaking injector on my Citroen C-crosser, how to fix the leak

And to finish, we’re going to check out 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 due to the pressures suffered. But think that the pressure in the circuit is enormous, especially on diesel engines. So you will have to take some safety measures:

  • Lower the pressure before any work is conducted…
  • 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:

  • Situate the source of the leak
  • Dismantle 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 specifically complex, but if you have the tiniest hesitation in the treatment of your injector that leaks on your Citroen C-crosser, we advise you to get closer to your motor mechanic to avoid any bad handling that could severely harm the condition of your Citroen C-crosser.
