Leaking injector on my petrol Citroen Jumper
It is crucial to know that the injectors on petrol and diesel engines are distinct, in reality, the difference in combustion between these two types of engines makes the injection distinct. The main difference lies in the pressure undergone 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 Jumper: The different leaks
It should be known that injector leaks on a Citroen Jumper equipped with a petrol engine are pretty rare. This is due to the much lower pressure in the petrol intake systems. However, 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 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 portion of the injector of your car, this one will occur from the junction with the engine and not with the rail as seen before.
Leaking injector on my diesel Citroen Jumper
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 Jumper: The different leaks
In the circumstance of leaking diesel injectors on your Citroen Jumper, there are three several types of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform as time passes, commonly 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 Jumper 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 feel an air noise and a compression loss. - If after checking you have oil leaking but it does not come from your injectors, we recommend you to consult this article content on the presence of oil leaking on your Citroen Jumper.
Leaking injector on my Citroen Jumper, how to fix the leak
And at last, we’re going to look at how to fix a leaking injector on your car. Frequently a leak is associated, 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 done…
- 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 regularly be limited to replacing the seals that have failed:
- Locate the source of the leak
- Dismantle 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 necessarily very hard, but if you have the slightest hesitation in the treatment of your injector that leaks on your Citroen Jumper, we recommend you to get closer to your motor mechanic to avoid any bad manipulation that could critically harm the condition of your Citroen Jumper.
