Leaking injector on my petrol Peugeot e-208
It is vital to know that the injectors on petrol and diesel engines are different, actually, the difference in combustion between these two sort of engines makes the injection different. 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 Peugeot e-208: The different leaks
It should be noted that injector leaks on a Peugeot e-208 equipped with a petrol engine are pretty infrequent. 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 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 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 Peugeot e-208
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system 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 Peugeot e-208: The different leaks
In the circumstance of leaking diesel injectors on your Peugeot e-208, there are three several sort of leaks:
- Leakage from the injector inlet:
In cases like this, it is an inlet pipe that will deform over time, 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 Peugeot e-208 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 bothersome, 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 checking you have oil leaking but it does not come from your injectors, we advise you to browse this article on the existence of oil leaking on your Peugeot e-208.
Leaking injector on my Peugeot e-208, 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 linked, as we have seen prior to this, to a worn seal caused by the pressures endured. But think that the pressure in the circuit is tremendous, specifically on diesel engines. So you will have to take some measures:
- Lower the pressure before any work is completed…
- 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 oftentimes be limited to changing the seals that have failed:
- Find 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 respect with the manufacturer’s standards.
