In the event you are alert of unusual signs on your vehicle, you are right to be worried, because a car represents a big annual budget and sudden malfunctions don’t reduce the costs. So what if you find that you have a leaking injector on your Honda HR V? You likely figured it out thanks to black/oily drips along your engine unit, or a troubled idle, or strange black smoke. These three manifestations are the main indicators of a leaking injector. As this problem can produce more serious engine problems on your car, we chose to prepare this content to help you ensure the failure of a leaking injector and treat it correctly. To do this, we will initially check out the circumstance of gasoline injectors and then at those of diesel injectors Honda HR V.
Leaking injector on my petrol Honda HR V
It is essential to know that the injectors on petrol and diesel engines are distinct, the truth is, the difference in combustion between these two types of engines makes the injection distinct. The essential 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 Honda HR V: The different leaks
It should be noted that injector leaks on a Honda HR V equipped with a petrol engine are pretty rare. This is resulting from the much lower pressure in the petrol intake systems. Nevertheless, there are two types 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 portion that is attached to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
Finally, 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 before.
Leaking injector on my diesel Honda HR V
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure 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 Honda HR V: The different leaks
In the circumstance of leaking diesel injectors on your Honda HR V, there are three several types of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform with time, commonly 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 Honda HR V 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 encounter an air noise and a compression loss. - If after checking you have oil leaking but it does not come from your injectors, we advise you to consult this content on the presence of oil leaking on your Honda HR V.
Leaking injector on my Honda HR V, how to fix the leak
And at last, we’re going to check out how to fix a leaking injector on your car. Oftentimes a leak is associated, as we have seen sooner, to a worn seal because of the pressures endured. But think that the pressure in the circuit is gigantic, specifically on diesel engines. So you will have to take some precautions:
- 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 frequently be restricted to replacing the seals that have failed:
- Discover the source of the leak
- Take apart the injector in question
- Change 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 complex, but if you have the tiniest hesitation in the treatment of your injector that leaks on your Honda HR V, we advise you to get closer to your auto mechanic to avoid any bad manipulation that could seriously harm the condition of your Honda HR V.
