In the event you are alert of irregular signs on your vehicle, you are right to be concerned, because a car represents a big annual budget and unexpected malfunctions don’t lower the bill. So what if you think that you have a leaking injector on your Peugeot 2008? You most likely figured it out thanks to black/oily drips along your engine, or a disturbed idle, or uncommon black smoke. These three signs of illness are the main signs of a leaking injector. As this troubles can lead to more severe engine concerns on your car, we decided to compose this content to help you ensure the failure of a leaking injector and treat it correctly. To achieve this, we will first check out the case of gasoline injectors and then at those of diesel injectors Peugeot 2008.
Leaking injector on my petrol Peugeot 2008
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 types 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 2008: The different leaks
It should be said that injector leaks on a Peugeot 2008 equipped with a petrol engine are rather infrequent. This is as a result of the much lower pressure in the petrol intake systems. Even so, there are two types 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 portion 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 encounter 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 before.
Leaking injector on my diesel Peugeot 2008
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 Peugeot 2008: The different leaks
In the case of leaking diesel injectors on your Peugeot 2008, there are three several types of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform as time passes, in most cases the leak will be at the clamping point. - Injector return leakage:
As its name reveals, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Peugeot 2008 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 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 consult this content on the presence of oil leaking on your Peugeot 2008.
Leaking injector on my Peugeot 2008, how to fix the leak
And to finish, we’re going to check out how to fix a leaking injector on your car. Oftentimes a leak is linked, as we have seen sooner, to a worn seal because of the pressures endured. But think that the pressure in the circuit is monumental, especially on diesel engines. So you will have to take some measures:
- Lower the pressure before any work is achieved…
- 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 frequently be limited to changing the seals that have failed:
- Discover the source of the leak
- Dismantle 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 very hard, but if you have the tiniest hesitation in the treatment of your injector that leaks on your Peugeot 2008, we advise you to get closer to your motor mechanic to avoid any bad handling that could critically harm the condition of your Peugeot 2008.
