In the event that you are informed of abnormal signs on your car, you are right to be worried, because a car represents a huge annual budget and unpredicted breakdowns don’t lower the bill. So what if you think that you have a leaking injector on your Ds Ds 3 Crossback? You likely figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or unconventional black smoke. These three manifestations are the main signals of a leaking injector. As this failure can lead to more serious engine problems on your car, we chose to publish this content page to help you verify the failure of a leaking injector and deal with it correctly. To achieve this, we will first of all take a look at the circumstance of gasoline injectors and then at those of diesel injectors Ds Ds 3 Crossback.
Leaking injector on my petrol Ds Ds 3 Crossback
It is vital to know that the injectors on petrol and diesel engines are different, actually, the difference in combustion between these two sort of engines makes the injection different. The key 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 Ds Ds 3 Crossback: The different leaks
It should be mentioned that injector leaks on a Ds Ds 3 Crossback equipped with a petrol engine are pretty infrequent. This is due to 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 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 part 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 Ds Ds 3 Crossback
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 Ds Ds 3 Crossback: The different leaks
In the circumstance of leaking diesel injectors on your Ds Ds 3 Crossback, there are three different sort of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform after a while, usually the leak will be at the clamping point. - Injector return leakage:
As its name implies, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Ds Ds 3 Crossback will be caused by an O-ring or its plastic tip that leaks. - Injector base leak:
This injection leak is one of the most bothersome, 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 advise you to consult this content page on the existence of oil leaking on your Ds Ds 3 Crossback.
Leaking injector on my Ds Ds 3 Crossback, how to fix the leak
And finally, we’re going to take a look at how to fix a leaking injector on your car. Very often 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 tremendous, especially on diesel engines. So you will have to take some measures:
- 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.
Regarding the repair part of your leak, it will very often be limited to changing the seals that have failed:
- Situate the source of the leak
- Dismantle the injector in question
- Replace the corresponding seal kit
- Reassemble the set up 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 smallest hesitation in the treatment of your injector that leaks on your Ds Ds 3 Crossback, we advise you to get closer to your motor mechanic to avoid any bad manipulation that could severely harm the condition of your Ds Ds 3 Crossback.
