In cases where you are informed of irregular signs on your vehicle, you are right to be concerned, because a car represents a massive annual budget and unpredicted breakdowns don’t reduce the expenses. So what if you feel as if you have a leaking injector on your Renault Clio 2 Campus? You most likely figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or strange black smoke. These three signs of illness are the main signs of a leaking injector. As this problem can end up in more severe engine complications on your car, we made a decision to publish this content to help you validate the failure of a leaking injector and treat it correctly. To do this, we will initially take a look at the case of gasoline injectors and then at those of diesel injectors Renault Clio 2 Campus.
Leaking injector on my petrol Renault Clio 2 Campus
It is essential to know that the injectors on petrol and diesel engines are distinct, in fact, the difference in combustion between these two types of engines makes the injection distinct. The biggest 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 Renault Clio 2 Campus: The different leaks
It should be noted that injector leaks on a Renault Clio 2 Campus equipped with a petrol engine are rather rare. This is resulting from 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 portion 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 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 sooner.
Leaking injector on my diesel Renault Clio 2 Campus
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 Renault Clio 2 Campus: The different leaks
In the case of leaking diesel injectors on your Renault Clio 2 Campus, there are three different types of leaks:
- Leakage from the injector inlet:
In this case, 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 reveals, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Renault Clio 2 Campus 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 feel 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 presence of oil leaking on your Renault Clio 2 Campus.
Leaking injector on my Renault Clio 2 Campus, 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 caused by the pressures endured. But think that the pressure in the circuit is monumental, especially 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.
Relating to the repair part of your leak, it will oftentimes be restricted 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 accordance with the manufacturer’s standards.
In all cases, these interventions are not automatically difficult, but if you have the tiniest uncertainty in the treatment of your injector that leaks on your Renault Clio 2 Campus, we recommend you to get closer to your auto mechanic to avoid any bad handling that could severely harm the condition of your Renault Clio 2 Campus.
