In the event you are aware of unusual symptoms on your car, you are right to be concerned, because a car represents a huge annual budget and unexpected breakdowns don’t lower the bill. So what if you feel like you have a leaking injector on your Honda E? You most likely figured it out thanks to black/oily drips along your engine unit, or a disturbed idle, or unconventional black smoke. These three symptoms are the main signs of a leaking injector. As this failure can produce more significant engine concerns on your car, we made a decision to prepare this content page to help you ensure the failure of a leaking injector and treat it correctly. To achieve this, we will initially take a look at the case of gasoline injectors and then at those of diesel injectors Honda E.


Leaking injector on my petrol Honda E

It is important to know that the injectors on petrol and diesel engines are different, in fact, the difference in combustion between these two types 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 Honda E: The different leaks

It should be noted that injector leaks on a Honda E equipped with a petrol engine are pretty rare. This is because of the much lower pressure in the petrol intake systems. However, there are two types 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 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 suffer 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 previously.

Leaking injector on my diesel Honda E

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 Honda E: The different leaks

In the case of leaking diesel injectors on your Honda E, there are three different types of leaks:

  • Leakage from the injector inlet:
    In cases like this, it is an inlet pipe that will deform with time, generally the leak will be at the clamping point.
  • Injector return leakage:
    As its name suggests, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Honda E 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 annoying, 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 examining you have oil leaking but it does not come from your injectors, we advise you to consult this content page on the existence of oil leaking on your Honda E.

Leaking injector on my Honda E, how to fix the leak

And to finish, we’re going to take a look at how to fix a leaking injector on your car. Oftentimes a leak is linked, as we have seen prior to this, to a worn seal because of the pressures endured. But think that the pressure in the circuit is enormous, especially on diesel engines. So you will have to take some measures:

  • Lower the pressure before any work is carried out…
  • Masking 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 regularly be limited to swapping the seals that have failed:

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

In all cases, these interventions are not inevitably very hard, but if you have the slightest hesitation in the treatment of your injector that leaks on your Honda E, we advise you to get closer to your mechanic to avoid any bad handling that could severely harm the condition of your Honda E.
