In cases where you are aware of irregular signs on your vehicle, you are right to be intrigued, because a car represents a big annual budget and unforeseen malfunctions don’t lower the expenses. So what if you feel as if you have a leaking injector on your Honda Element? You most likely figured it out thanks to black/oily drips along your engine, or a troubled idle, or uncommon black smoke. These three symptoms are the main signs of a leaking injector. As this failure can cause more severe engine trouble on your car, we chose to write this content to help you ensure the failure of a leaking injector and treat it correctly. To do so, we will first of all take a look at the case of gasoline injectors and then at those of diesel injectors Honda Element.
Leaking injector on my petrol Honda Element
It is vital to know that the injectors on petrol and diesel engines are different, in reality, the difference in combustion between these two kind 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 Honda Element: The different leaks
It should be mentioned that injector leaks on a Honda Element equipped with a petrol engine are pretty infrequent. This is because of the much lower pressure in the petrol intake systems. However, there are two kind 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 part that is linked 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 part 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 Element
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 Element: The different leaks
In the case of leaking diesel injectors on your Honda Element, there are three different kind of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform along with time, commonly the leak will be at the clamping point. - Injector return leakage:
As its name indicates, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Honda Element 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 encounter an air noise and a compression loss. - If after checking you have oil leaking but it does not come from your injectors, we recommend you to browse this content on the existence of oil leaking on your Honda Element.
Leaking injector on my Honda Element, how to fix the leak
And at last, we’re going to take a look at how to fix a leaking injector on your car. Regularly a leak is linked, as we have seen previously, to a worn seal due to the pressures endured. But think that the pressure in the circuit is gigantic, specifically on diesel engines. So you will have to take some measures:
- Lower the pressure before any work is conducted…
- 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 restricted to replacing the seals that have failed:
- Locate 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 very hard, but if you have the tiniest hesitation in the treatment of your injector that leaks on your Honda Element, we recommend you to get closer to your auto technician to avoid any bad manipulation that could seriously harm the condition of your Honda Element.
