In the event that you are aware of unusual signs on your car, you are right to be intrigued, because a car represents a huge annual budget and unexpected malfunctions don’t lower the bill. So what if you feel as if you have a leaking injector on your Honda Insight? You likely figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or unusual black smoke. These three manifestations are the main symptoms of a leaking injector. As this problem can bring about more critical engine trouble on your car, we made a decision to produce this content to help you confirm the failure of a leaking injector and deal with it correctly. To do this, we will first of all check out the circumstance of gasoline injectors and then at those of diesel injectors Honda Insight.
Leaking injector on my petrol Honda Insight
It is essential to know that the injectors on petrol and diesel engines are distinct, in fact, the difference in combustion between these two sort of engines makes the injection distinct. 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 Honda Insight: The different leaks
It should be noted that injector leaks on a Honda Insight equipped with a petrol engine are pretty infrequent. 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 plausible that you have a leak from the top of the injector, this is the portion that is connected to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
Finally, 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 before.
Leaking injector on my diesel Honda Insight
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure generates 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 Insight: The different leaks
In the circumstance of leaking diesel injectors on your Honda Insight, there are three several 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 concerns the management of the fuel return in the injector, this time the injector that leaks on your Honda Insight will be caused 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 browse this content on the presence of oil leaking on your Honda Insight.
Leaking injector on my Honda Insight, how to fix the leak
And at last, we’re going to check out how to fix a leaking injector on your car. Very often a leak is connected, 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 tremendous, especially on diesel engines. So you will have to take some precautions:
- 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.
Relating to the repair part of your leak, it will oftentimes be limited to swapping the seals that have failed:
- Discover 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 respect with the manufacturer’s standards.
In all situations, these interventions are not automatically complicated, but if you have the tiniest uncertainty in the treatment of your injector that leaks on your Honda Insight, we advise you to get closer to your auto technician to avoid any bad handling that could severely harm the condition of your Honda Insight.
