If you are alert of unusual symptoms on your automobile, you are right to be intrigued, because a car represents a massive annual budget and unexpected malfunctions don’t reduce the expenses. So what if you feel as if you have a leaking injector on your Peugeot 5008? You most likely figured it out thanks to black/oily drips along your engine, or a troubled idle, or strange black smoke. These three manifestations are the main indicators of a leaking injector. As this troubles can end up in more serious engine trouble on your car, we chose to compose this content to help you verify the failure of a leaking injector and deal with it correctly. To do so, we will first look at the case of gasoline injectors and then at those of diesel injectors Peugeot 5008.
Leaking injector on my petrol Peugeot 5008
It is fundamental to know that the injectors on petrol and diesel engines are different, actually, the difference in combustion between these two sort 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 5008: The different leaks
It should be mentioned that injector leaks on a Peugeot 5008 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 sort 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 part that is connected 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 come from the junction with the engine and not with the rail as seen before.
Leaking injector on my diesel Peugeot 5008
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system produces 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 5008: The different leaks
In the case of leaking diesel injectors on your Peugeot 5008, there are three several sort of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform with time, generally the leak will be at the clamping point. - Injector return leakage:
As its name implies, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Peugeot 5008 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 5008.
Leaking injector on my Peugeot 5008, how to fix the leak
And finally, 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 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 done…
- 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 very often be restricted to changing the seals that have failed:
- Locate the source of the leak
- Dismantle the injector in question
- Replace the corresponding seal kit
- Reassemble the set up and tighten with a torque wrench in accordance with the manufacturer’s standards.
In all cases, these interventions are not specifically complex, but if you have the slightest hesitation in the treatment of your injector that leaks on your Peugeot 5008, we advise you to get closer to your auto mechanic to avoid any bad manipulation that could seriously harm the condition of your Peugeot 5008.
