In cases where you are aware of abnormal signs on your automobile, you are right to be worried, because a car represents a massive annual budget and unexpected breakdowns don’t reduce the bill. So what if you sense that you have a leaking injector on your Citroen Jumpy 2? You almost certainly figured it out thanks to black/oily drips along your engine unit, or a disturbed idle, or unconventional black smoke. These three signs of illness are the main signals of a leaking injector. As this problem can bring on more significant engine trouble on your car, we thought we would publish this content page to help you confirm the failure of a leaking injector and treat it properly. To do this, we will first look at the circumstance of gasoline injectors and then at those of diesel injectors Citroen Jumpy 2.

Leaking injector on my petrol Citroen Jumpy 2

It is vital to know that the injectors on petrol and diesel engines are different, the reality is, the difference in combustion between these two sort of engines makes the injection different. 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 Jumpy 2: The different leaks

It should be known that injector leaks on a Citroen Jumpy 2 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 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 suffer 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 Citroen Jumpy 2

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 Jumpy 2: The different leaks

In the circumstance of leaking diesel injectors on your Citroen Jumpy 2, there are three several sort of leaks:

  • Leakage from the injector inlet:
    In cases like this, it is an inlet pipe that will deform over time, in most cases the leak will be at the clamping point.
  • Injector return leakage:
    As its name indicates, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Citroen Jumpy 2 will be the result 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 feel an air noise and a compression loss.
  • If after checking you have oil leaking but it does not come from your injectors, we encourage you to read this content page on the existence of oil leaking on your Citroen Jumpy 2.

Leaking injector on my Citroen Jumpy 2, how to fix the leak

And finally, we’re going to look at how to fix a leaking injector on your car. Oftentimes a leak is associated, as we have seen previously, to a worn seal as a result of the pressures suffered. But think that the pressure in the circuit is tremendous, specifically on diesel engines. So you will have to take some 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.

Regarding the repair part of your leak, it will very often be limited to replacing 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 accordance with the manufacturer’s standards.

In all cases, these interventions are not specifically difficult, but if you have the tiniest hesitation in the treatment of your injector that leaks on your Citroen Jumpy 2, we encourage you to get closer to your auto technician to avoid any bad manipulation that could severely harm the condition of your Citroen Jumpy 2.
