Whenever you are alert of irregular signs on your automobile, you are right to be preoccupied, because a car represents a massive annual budget and sudden malfunctions don’t reduce the expenses. So what if you sense that you have a leaking injector on your Peugeot 208? You probably figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or unconventional black smoke. These three manifestations are the main signs of a leaking injector. As this problem can bring about more critical engine concerns on your car, we chose to write this content page to help you confirm the failure of a leaking injector and handle it correctly. To achieve this, we will first take a look at the case of gasoline injectors and then at those of diesel injectors Peugeot 208.
Leaking injector on my petrol Peugeot 208
It is vital to know that the injectors on petrol and diesel engines are different, the truth is, 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 208: The different leaks
It should be noted that injector leaks on a Peugeot 208 equipped with a petrol engine are rather rare. This is caused by the much lower pressure in the petrol intake systems. Even so, 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 encounter a leak coming from the lower part of the injector of your car, this one will come from the junction with the engine and not with the rail as seen sooner.
Leaking injector on my diesel Peugeot 208
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 Peugeot 208: The different leaks
In the case of leaking diesel injectors on your Peugeot 208, there are three different sort of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform as time passes, usually 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 208 will be the result 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 feel an air noise and a compression loss. - If after examining you have oil leaking but it does not come from your injectors, we suggest you to browse this content page on the presence of oil leaking on your Peugeot 208.
Leaking injector on my Peugeot 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. Oftentimes a leak is linked, as we have seen previously, to a worn seal caused by the pressures suffered. But think that the pressure in the circuit is gigantic, specifically 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.
Relating to the repair part of your leak, it will very often be restricted to swapping the seals that have failed:
- Find out 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 accordance with the manufacturer’s standards.
In all situations, these interventions are not necessarily difficult, but if you have the tiniest uncertainty in the treatment of your injector that leaks on your Peugeot 208, we suggest you to get closer to your repair shop to avoid any bad manipulation that could critically harm the condition of your Peugeot 208.
