In cases where you are alert of irregular signs on your automobile, you are right to be concerned, because a car represents a big annual budget and surprising breakdowns don’t lower the bill. So what if you sense that you have a leaking injector on your iveco daily? 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 troubles can end up in more significant engine trouble on your car, we decided to publish this content to help you validate the failure of a leaking injector and deal with it properly. To achieve this, we will first take a look at the case of gasoline injectors and then at those of diesel injectors iveco daily.
Leaking injector on my petrol iveco daily
It is vital to know that the injectors on petrol and diesel engines are distinct, in fact, the difference in combustion between these two kind of engines makes the injection distinct. The main 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 iveco daily: The different leaks
It should be mentioned that injector leaks on a iveco daily equipped with a petrol engine are rather infrequent. This is resulting from the much lower pressure in the petrol intake systems. Even so, 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 component that is attached 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 appear from the junction with the engine and not with the rail as seen previously.
Leaking injector on my diesel iveco daily
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 iveco daily: The different leaks
In the case of leaking diesel injectors on your iveco daily, there are three several kind of leaks:
- Leakage from the injector inlet:
In this instance, 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 iveco daily will be the result of 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 feel an air noise and a compression loss. - If after verifying 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 iveco daily.
Leaking injector on my iveco daily, 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 associated, as we have seen previously, 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 safety measures:
- Lower the pressure before any work is conducted…
- Covering 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 oftentimes be limited to replacing the seals that have failed:
- Find out the source of the leak
- Dismantle 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 cases, these interventions are not specifically very hard, but if you have the tiniest hesitation in the treatment of your injector that leaks on your iveco daily, we advise you to get closer to your mechanic to avoid any bad handling that could significantly harm the condition of your iveco daily.
Whenever you have any additional questions about the iveco daily, do not hesitate to consult our iveco daily category.
