If you are informed of irregular symptoms on your car, you are right to be worried, because a car represents a huge annual budget and surprising breakdowns don’t reduce the costs. So what if you think that you have a leaking injector on your Peugeot Partner? You probably figured it out thanks to black/oily drips along your engine unit, or a disturbed idle, or uncommon black smoke. These three signs of illness are the main signals of a leaking injector. As this problem can produce more critical engine concerns on your car, we thought we would write this article to help you ensure the failure of a leaking injector and handle it correctly. To achieve this, we will first look at the case of gasoline injectors and then at those of diesel injectors Peugeot Partner.
Leaking injector on my petrol Peugeot Partner
It is essential to know that the injectors on petrol and diesel engines are different, the reality is, the difference in combustion between these two types of engines makes the injection different. The essential 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 Partner: The different leaks
It should be mentioned that injector leaks on a Peugeot Partner equipped with a petrol engine are pretty rare. This is as a result of the much lower pressure in the petrol intake systems. Nevertheless, there are two types of leaks:
- Leakage from the top of the injector:
It is conceivable that you have a leak from the top of the injector, this is the part that is connected 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 portion of the injector of your car, this one will appear from the junction with the engine and not with the rail as seen previously.
Leaking injector on my diesel Peugeot Partner
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 Partner: The different leaks
In the case of leaking diesel injectors on your Peugeot Partner, there are three different types of leaks:
- Leakage from the injector inlet:
In cases like this, it is an inlet pipe that will deform along with time, commonly 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 Partner 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 encounter 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 article on the existence of oil leaking on your Peugeot Partner.
Leaking injector on my Peugeot Partner, how to fix the leak
And at last, we’re going to look at how to fix a leaking injector on your car. Oftentimes a leak is connected, as we have seen previously, to a worn seal because 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 achieved…
- Masking you to avoid the risk of fuel spillage
- NEVER work on a running diesel engine injector.
Concerning the repair part of your leak, it will very often be restricted to replacing the seals that have failed:
- Situate 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 cases, these interventions are not necessarily complex, but if you have the tiniest doubt in the treatment of your injector that leaks on your Peugeot Partner, we advise you to get closer to your motor mechanic to avoid any bad handling that could significantly harm the condition of your Peugeot Partner.
