If you are aware of unusual signs on your automobile, you are right to be preoccupied, because a car represents a big annual budget and sudden breakdowns don’t reduce the costs. So what if you think that you have a leaking injector on your Peugeot 3008? You almost certainly figured it out thanks to black/oily drips along your engine, or a troubled idle, or uncommon black smoke. These three symptoms are the main signals of a leaking injector. As this problem 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 deal with it properly. To achieve this, we will initially look at the case of gasoline injectors and then at those of diesel injectors Peugeot 3008.
Leaking injector on my petrol Peugeot 3008
It is essential to know that the injectors on petrol and diesel engines are distinct, the truth is, the difference in combustion between these two kind of engines makes the injection distinct. The main difference lies in the pressure experienced 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 3008: The different leaks
It should be mentioned that injector leaks on a Peugeot 3008 equipped with a petrol engine are rather infrequent. This is as a result of the much lower pressure in the petrol intake systems. Nevertheless, there are two kind 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 portion that is connected 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 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 Peugeot 3008
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 3008: The different leaks
In the case of leaking diesel injectors on your Peugeot 3008, there are three several kind of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform along with time, usually the leak will be at the clamping point. - Injector return leakage:
As its name implies, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Peugeot 3008 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 troublesome, 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 browse this content on the presence of oil leaking on your Peugeot 3008.
Leaking injector on my Peugeot 3008, how to fix the leak
And at last, we’re going to look at how to fix a leaking injector on your car. Very often a leak is connected, as we have seen prior to this, to a worn seal due to the pressures suffered. But think that the pressure in the circuit is gigantic, specifically on diesel engines. So you will have to take some precautions:
- 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.
Regarding the repair part of your leak, it will frequently be limited to replacing 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 accordance with the manufacturer’s standards.
In all situations, these interventions are not specifically difficult, but if you have the tiniest doubt in the treatment of your injector that leaks on your Peugeot 3008, we recommend you to get closer to your auto mechanic to avoid any bad handling that could severely harm the condition of your Peugeot 3008.
