If you are informed of unusual symptoms on your vehicle, you are right to be preoccupied, because a car represents a big annual budget and surprising malfunctions don’t lower the bill. So what if you sense that you have a leaking injector on your Peugeot 207? You likely figured it out thanks to black/oily drips along your engine, or a disturbed idle, or unusual black smoke. These three signs of illness are the main indicators of a leaking injector. As this problem can bring about more critical engine complications on your car, we made a decision to write this content page to help you ensure the failure of a leaking injector and handle it correctly. To accomplish this, we will initially look into the case of gasoline injectors and then at those of diesel injectors Peugeot 207.
Leaking injector on my petrol Peugeot 207
It is crucial to know that the injectors on petrol and diesel engines are different, the reality is, the difference in combustion between these two sort of engines makes the injection different. The key 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 207: The different leaks
It should be mentioned that injector leaks on a Peugeot 207 equipped with a petrol engine are pretty infrequent. This is resulting from the much lower pressure in the petrol intake systems. However, there are two sort 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 attached to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
At last, you may experience a leak coming from the lower portion of the injector of your car, this one will come from the junction with the engine and not with the rail as seen before.
Leaking injector on my diesel Peugeot 207
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 207: The different leaks
In the case of leaking diesel injectors on your Peugeot 207, there are three different sort of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform in the long run, 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 207 will be caused 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 encounter an air noise and a compression loss. - If after verifying you have oil leaking but it does not come from your injectors, we recommend you to read this content page on the presence of oil leaking on your Peugeot 207.
Leaking injector on my Peugeot 207, how to fix the leak
And finally, we’re going to look into how to fix a leaking injector on your car. Oftentimes a leak is linked, 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, especially on diesel engines. So you will have to take some measures:
- Lower the pressure before any work is completed…
- Covering 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 regularly be limited to replacing the seals that have failed:
- Find out the source of the leak
- Take apart 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 cases, these interventions are not necessarily complicated, but if you have the slightest doubt in the treatment of your injector that leaks on your Peugeot 207, we recommend you to get closer to your motor mechanic to avoid any bad handling that could critically harm the condition of your Peugeot 207.
