In the event that you are informed of irregular signs on your vehicle, you are right to be concerned, because a car represents a big annual budget and surprising malfunctions don’t reduce the bill. So what if you think that you have a leaking injector on your Ford Edge? You most likely figured it out thanks to black/oily drips along your engine, or a disturbed idle, or strange black smoke. These three signs of illness are the main signals of a leaking injector. As this problem can produce more serious engine trouble on your car, we decided to write this content page to help you confirm the failure of a leaking injector and deal with it correctly. To accomplish this, we will first look into the case of gasoline injectors and then at those of diesel injectors Ford Edge.
Leaking injector on my petrol Ford Edge
It is fundamental 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 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 Ford Edge: The different leaks
It should be known that injector leaks on a Ford Edge equipped with a petrol engine are rather infrequent. This is due to 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 portion that is attached to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
Finally, you may encounter 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 previously.
Leaking injector on my diesel Ford Edge
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 Ford Edge: The different leaks
In the case of leaking diesel injectors on your Ford Edge, there are three several kind of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform as time passes, in most cases the leak will be at the clamping point. - Injector return leakage:
As its name suggests, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Ford Edge 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 examining 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 Ford Edge.
Leaking injector on my Ford Edge, how to fix the leak
And to finish, we’re going to look into how to fix a leaking injector on your car. Very often a leak is connected, as we have seen sooner, to a worn seal caused by the pressures suffered. But think that the pressure in the circuit is tremendous, specifically on diesel engines. So you will have to take some safety 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 frequently be restricted to changing the seals that have failed:
- Find out 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 situations, these interventions are not inevitably complex, but if you have the smallest doubt in the treatment of your injector that leaks on your Ford Edge, we recommend you to get closer to your repair shop to avoid any bad manipulation that could significantly harm the condition of your Ford Edge.
