You likely figured it out thanks to black/oily drips along your engine motor, or a disturbed idle, or unusual black smoke. These three symptoms are the main indicators of a leaking injector. As this troubles can end up in more critical engine trouble on your car, we decided to compose this article to help you verify the failure of a leaking injector and deal with it correctly. To do this, we will first of all take a look at the circumstance of gasoline injectors and then at those of diesel injectors Peugeot Partner 2.
Leaking injector on my petrol Peugeot Partner 2
It is crucial to know that the injectors on petrol and diesel engines are distinct, in fact, the difference in combustion between these two kind of engines makes the injection distinct. 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 Partner 2: The different leaks
It should be mentioned that injector leaks on a Peugeot Partner 2 equipped with a petrol engine are rather rare. This is caused by the much lower pressure in the petrol intake systems. However, 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 component 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 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 before.
Leaking injector on my diesel Peugeot Partner 2
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 Partner 2: The different leaks
In the circumstance of leaking diesel injectors on your Peugeot Partner 2, there are three several kind of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform as time passes, commonly the leak will be at the clamping point. - Injector return leakage:
As its name reveals, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Peugeot Partner 2 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 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 examining you have oil leaking but it does not come from your injectors, we suggest you to read this article on the presence of oil leaking on your Peugeot Partner 2.
Leaking injector on my Peugeot Partner 2, how to fix the leak
And to finish, we’re going to take a look at how to fix a leaking injector on your car. Very often a leak is associated, as we have seen sooner, to a worn seal as a result of the pressures endured. But think that the pressure in the circuit is enormous, specifically on diesel engines. So you will have to take some measures:
- Lower the pressure before any work is carried out…
- 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 replacing the seals that have failed:
- Situate 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 automatically difficult, but if you have the smallest uncertainty in the treatment of your injector that leaks on your Peugeot Partner 2, we suggest you to get closer to your mechanic to avoid any bad handling that could seriously harm the condition of your Peugeot Partner 2.
