You likely figured it out thanks to black/oily drips along your engine unit, or a troubled idle, or unconventional black smoke. These three manifestations are the main signals of a leaking injector. As this failure can end up in more critical engine complications on your car, we thought we would prepare this content page to help you verify the failure of a leaking injector and treat it correctly. To accomplish this, we will first check out the circumstance of gasoline injectors and then at those of diesel injectors Citroen C15.
Leaking injector on my petrol Citroen C15
It is essential to know that the injectors on petrol and diesel engines are different, in fact, 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 C15: The different leaks
It should be noted that injector leaks on a Citroen C15 equipped with a petrol engine are pretty rare. This is because of 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 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 suffer 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 previously.
Leaking injector on my diesel Citroen C15
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure 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 Citroen C15: The different leaks
In the circumstance of leaking diesel injectors on your Citroen C15, there are three several sort of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform in the long run, usually the leak will be at the clamping point. - Injector return leakage:
As its name indicates, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Citroen C15 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 annoying, it is the junction between the engine and the injector nose that leaks at a copper seal, you should encounter 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 browse this content page on the presence of oil leaking on your Citroen C15.
Leaking injector on my Citroen C15, how to fix the leak
And at last, we’re going to check out how to fix a leaking injector on your car. Very often a leak is linked, as we have seen sooner, to a worn seal as a result of the pressures endured. But think that the pressure in the circuit is tremendous, especially on diesel engines. So you will have to take some safety measures:
- Lower the pressure before any work is conducted…
- 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 frequently be restricted to changing the seals that have failed:
- Locate the source of the leak
- Take apart the injector in question
- Change 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 inevitably complex, but if you have the tiniest doubt in the treatment of your injector that leaks on your Citroen C15, we advise you to get closer to your auto technician to avoid any bad manipulation that could significantly harm the condition of your Citroen C15.
