As this troubles can lead to more critical engine trouble on your car, we made a decision to prepare this content page to help you verify the failure of a leaking injector and handle it correctly.

Leaking injector on my petrol Citroen C-zero
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 essential 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 Citroen C-zero: The different leaks
It should be mentioned that injector leaks on a Citroen C-zero equipped with a petrol engine are rather rare. This is due to the much lower pressure in the petrol intake systems. However, 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 component that is linked 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 come from the junction with the engine and not with the rail as seen sooner.
Leaking injector on my diesel Citroen C-zero
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system 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 Citroen C-zero: The different leaks
In the circumstance of leaking diesel injectors on your Citroen C-zero, there are three different sort of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform as time passes, in most cases 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 Citroen C-zero 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 experience 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 page on the presence of oil leaking on your Citroen C-zero.
Leaking injector on my Citroen C-zero, how to fix the leak
And finally, we’re going to look into how to fix a leaking injector on your car. Very often a leak is linked, as we have seen sooner, to a worn seal due to 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 completed…
- 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 regularly be limited to changing the seals that have failed:
- Identify 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 specifically difficult, but if you have the slightest uncertainty in the treatment of your injector that leaks on your Citroen C-zero, we advise you to get closer to your auto mechanic to avoid any bad manipulation that could significantly harm the condition of your Citroen C-zero.
