In the event you are aware of unusual signs on your vehicle, you are right to be concerned, because a car represents a huge annual budget and surprising malfunctions don’t reduce the costs. So what if you feel as if you have a leaking injector on your Renault Latitude? 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 symptoms of a leaking injector. As this problem can bring about more severe engine trouble on your car, we thought we would prepare this article to help you validate the failure of a leaking injector and deal with it correctly. To accomplish this, we will initially take a look at the circumstance of gasoline injectors and then at those of diesel injectors Renault Latitude.
Leaking injector on my petrol Renault Latitude
It is crucial to know that the injectors on petrol and diesel engines are distinct, the reality is, the difference in combustion between these two kind of engines makes the injection distinct. The main 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 Latitude: The different leaks
It should be known that injector leaks on a Renault Latitude equipped with a petrol engine are rather infrequent. This is as a result of 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 part that is attached 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 come from the junction with the engine and not with the rail as seen before.
Leaking injector on my diesel Renault Latitude
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 Renault Latitude: The different leaks
In the circumstance of leaking diesel injectors on your Renault Latitude, there are three different kind of leaks:
- Leakage from the injector inlet:
In cases like this, it is an inlet pipe that will deform with time, generally 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 Renault Latitude 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 troublesome, it is the junction between the engine and the injector nose that leaks at a copper seal, you should experience an air noise and a compression loss. - If after examining you have oil leaking but it does not come from your injectors, we encourage you to consult this article on the presence of oil leaking on your Renault Latitude.
Leaking injector on my Renault Latitude, 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. Oftentimes a leak is associated, as we have seen prior to this, to a worn seal as a result of the pressures endured. But think that the pressure in the circuit is enormous, specifically on diesel engines. So you will have to take some precautions:
- Lower the pressure before any work is achieved…
- Masking you to avoid the risk of fuel spillage
- NEVER work on a running diesel engine injector.
Concerning the repair part of your leak, it will regularly be restricted 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 accordance with the manufacturer’s standards.
In all cases, these interventions are not automatically complex, but if you have the slightest hesitation in the treatment of your injector that leaks on your Renault Latitude, we encourage you to get closer to your mechanic to avoid any bad handling that could severely harm the condition of your Renault Latitude.
