In cases where you are alert of abnormal signs on your vehicle, you are right to be intrigued, because a car represents a huge annual budget and surprising breakdowns don’t reduce the bill. So what if you think that you have a leaking injector on your Peugeot Bipper? You likely figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or unusual black smoke. These three symptoms are the main symptoms of a leaking injector. As this troubles can produce more critical engine trouble on your car, we decided to publish this content page to help you confirm the failure of a leaking injector and deal with it properly. To do so, we will first look at the circumstance of gasoline injectors and then at those of diesel injectors Peugeot Bipper.
Leaking injector on my petrol Peugeot Bipper
It is crucial to know that the injectors on petrol and diesel engines are distinct, actually, the difference in combustion between these two sort of engines makes the injection distinct. The essential 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 Peugeot Bipper: The different leaks
It should be noted that injector leaks on a Peugeot Bipper 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 possible that you have a leak from the top of the injector, this is the component 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 part of the injector of your car, this one will occur from the junction with the engine and not with the rail as seen sooner.
Leaking injector on my diesel Peugeot Bipper
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 Peugeot Bipper: The different leaks
In the circumstance of leaking diesel injectors on your Peugeot Bipper, there are three different sort of leaks:
- Leakage from the injector inlet:
In cases like this, it is an inlet pipe that will deform along 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 Peugeot Bipper 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 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 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 Peugeot Bipper.
Leaking injector on my Peugeot Bipper, how to fix the leak
And finally, we’re going to look at how to fix a leaking injector on your car. Regularly a leak is linked, as we have seen sooner, to a worn seal caused by the pressures endured. But think that the pressure in the circuit is gigantic, specifically on diesel engines. So you will have to take some safety measures:
- Lower the pressure before any work is conducted…
- Masking 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 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 cases, these interventions are not necessarily complicated, but if you have the smallest uncertainty in the treatment of your injector that leaks on your Peugeot Bipper, we advise you to get closer to your auto technician to avoid any bad manipulation that could significantly harm the condition of your Peugeot Bipper.
