If you are aware of abnormal symptoms on your car, you are right to be concerned, because a car represents a big annual budget and surprising malfunctions don’t lower the costs. So what if you feel as if you have a leaking injector on your Citroen C4 Spacetourer? You almost certainly figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or strange black smoke. These three symptoms are the main symptoms of a leaking injector. As this failure can bring on more significant engine problems on your car, we thought we would prepare this article content to help you ensure the failure of a leaking injector and deal with it correctly. To do this, we will first check out the case of gasoline injectors and then at those of diesel injectors Citroen C4 Spacetourer.
Leaking injector on my petrol Citroen C4 Spacetourer
It is vital to know that the injectors on petrol and diesel engines are distinct, the reality is, the difference in combustion between these two sort of engines makes the injection distinct. The biggest 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 C4 Spacetourer: The different leaks
It should be said that injector leaks on a Citroen C4 Spacetourer equipped with a petrol engine are pretty infrequent. This is because of 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 component that is linked to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
Finally, you may experience 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 before.
Leaking injector on my diesel Citroen C4 Spacetourer
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 Citroen C4 Spacetourer: The different leaks
In the case of leaking diesel injectors on your Citroen C4 Spacetourer, there are three different sort of leaks:
- Leakage from the injector inlet:
In cases like this, it is an inlet pipe that will deform with time, commonly the leak will be at the clamping point. - Injector return leakage:
As its name suggests, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Citroen C4 Spacetourer will be caused 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 suggest you to consult this article content on the presence of oil leaking on your Citroen C4 Spacetourer.
Leaking injector on my Citroen C4 Spacetourer, 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 connected, as we have seen sooner, to a worn seal due to the pressures endured. But think that the pressure in the circuit is monumental, specifically on diesel engines. So you will have to take some precautions:
- 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.
Relating to the repair part of your leak, it will oftentimes be restricted to swapping the seals that have failed:
- Discover the source of the leak
- Take apart the injector in question
- Replace 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 necessarily difficult, but if you have the smallest doubt in the treatment of your injector that leaks on your Citroen C4 Spacetourer, we suggest you to get closer to your auto technician to avoid any bad handling that could critically harm the condition of your Citroen C4 Spacetourer.
