In the event that you are informed of abnormal symptoms on your automobile, you are right to be concerned, because a car represents a huge annual budget and sudden malfunctions don’t reduce the bill. So what if you feel like you have a leaking injector on your Citroen C1? You probably figured it out thanks to black/oily drips along your engine unit, or a troubled idle, or uncommon black smoke. These three manifestations are the main signals of a leaking injector. As this failure can end up in more severe engine complications on your car, we chose to produce this content page to help you verify 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 Citroen C1.
Leaking injector on my petrol Citroen C1
It is crucial to know that the injectors on petrol and diesel engines are different, the reality is, the difference in combustion between these two types 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 Citroen C1: The different leaks
It should be known that injector leaks on a Citroen C1 equipped with a petrol engine are pretty infrequent. This is resulting from the much lower pressure in the petrol intake systems. Nevertheless, 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 part that is connected 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 occur from the junction with the engine and not with the rail as seen previously.
Leaking injector on my diesel Citroen C1
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 Citroen C1: The different leaks
In the case of leaking diesel injectors on your Citroen C1, there are three different types of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform as time passes, generally the leak will be at the clamping point. - Injector return leakage:
As its name implies, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Citroen C1 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 find an air noise and a compression loss. - If after examining you have oil leaking but it does not come from your injectors, we suggest you to consult this content page on the presence of oil leaking on your Citroen C1.
Leaking injector on my Citroen C1, how to fix the leak
And finally, we’re going to take a look at how to fix a leaking injector on your car. Frequently a leak is connected, as we have seen previously, to a worn seal due to the pressures endured. But think that the pressure in the circuit is enormous, especially on diesel engines. So you will have to take some measures:
- Lower the pressure before any work is achieved…
- Covering 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 very often be restricted to swapping the seals that have failed:
- Locate 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 cases, these interventions are not necessarily complex, but if you have the slightest doubt in the treatment of your injector that leaks on your Citroen C1, we suggest you to get closer to your repair shop to avoid any bad handling that could significantly harm the condition of your Citroen C1.
