In the event that you are aware of unusual symptoms on your car, you are right to be intrigued, because a car represents a big annual budget and unpredicted breakdowns don’t reduce the bill. So what if you sense that you have a leaking injector on your Peugeot 106? You probably figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or unusual black smoke. These three symptoms are the main signals of a leaking injector. As this problem can bring on more severe engine trouble on your car, we chose to publish this article to help you confirm the failure of a leaking injector and deal with it properly. To accomplish this, we will first look into the circumstance of gasoline injectors and then at those of diesel injectors Peugeot 106.

Leaking injector on my petrol Peugeot 106

It is fundamental to know that the injectors on petrol and diesel engines are different, in reality, the difference in combustion between these two sort of engines makes the injection different. The essential 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 Peugeot 106: The different leaks

It should be noted that injector leaks on a Peugeot 106 equipped with a petrol engine are pretty rare. This is caused by the much lower pressure in the petrol intake systems. Nevertheless, there are two sort of leaks:

  • Leakage from the top of the injector:
    It is possible 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:
    At last, you may encounter a leak coming from the lower portion 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 Peugeot 106

Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system produces 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 Peugeot 106: The different leaks

In the circumstance of leaking diesel injectors on your Peugeot 106, there are three different sort of leaks:

  • Leakage from the injector inlet:
    In this instance, it is an inlet pipe that will deform after a while, commonly the leak will be at the clamping point.
  • Injector return leakage:
    As its name reveals, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Peugeot 106 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 verifying you have oil leaking but it does not come from your injectors, we encourage you to read this article on the existence of oil leaking on your Peugeot 106.

Leaking injector on my Peugeot 106, 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 connected, as we have seen sooner, 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 done…
  • 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 frequently be limited to replacing the seals that have failed:

  • Situate 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 difficult, but if you have the smallest uncertainty in the treatment of your injector that leaks on your Peugeot 106, we encourage you to get closer to your auto mechanic to avoid any bad manipulation that could severely harm the condition of your Peugeot 106.
