In cases where you are alert of abnormal symptoms on your vehicle, you are right to be preoccupied, because a car represents a massive annual budget and unforeseen breakdowns don’t lower the bill. So what if you find that you have a leaking injector on your Ford Ecosport? You almost certainly figured it out thanks to black/oily drips along your engine motor, or a disturbed idle, or strange black smoke. These three manifestations are the main signs of a leaking injector. As this problem can lead to more serious engine complications on your car, we chose to write this content page to help you verify the failure of a leaking injector and deal with it properly. To achieve this, we will first take a look at the circumstance of gasoline injectors and then at those of diesel injectors Ford Ecosport.
Leaking injector on my petrol Ford Ecosport
It is essential to know that the injectors on petrol and diesel engines are distinct, the truth is, the difference in combustion between these two sort of engines makes the injection distinct. The main 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 Ford Ecosport: The different leaks
It should be noted that injector leaks on a Ford Ecosport equipped with a petrol engine are pretty infrequent. This is because of 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 possible 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 part of the injector of your car, this one will come from the junction with the engine and not with the rail as seen sooner.
Leaking injector on my diesel Ford Ecosport
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 Ford Ecosport: The different leaks
In the circumstance of leaking diesel injectors on your Ford Ecosport, there are three several sort of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform as time passes, generally the leak will be at the clamping point.
- Injector return leakage:
As its name implies, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Ford Ecosport 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 feel an air noise and a compression loss.
- If after verifying you have oil leaking but it does not come from your injectors, we advise you to read this content page on the existence of oil leaking on your Ford Ecosport.
Leaking injector on my Ford Ecosport, 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. Oftentimes a leak is linked, as we have seen previously, to a worn seal as a result of the pressures suffered. But think that the pressure in the circuit is tremendous, especially on diesel engines. So you will have to take some precautions:
- Lower the pressure before any work is done…
- Covering 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 oftentimes be restricted to swapping the seals that have failed:
- Find 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 cases, these interventions are not inevitably complex, but if you have the tiniest doubt in the treatment of your injector that leaks on your Ford Ecosport, we advise you to get closer to your motor mechanic to avoid any bad manipulation that could severely harm the condition of your Ford Ecosport.
