In the event that you are aware of abnormal symptoms on your car, you are right to be preoccupied, because a car represents a huge annual budget and unpredicted breakdowns don’t lower the bill. So what if you sense that you have a leaking injector on your Ford Escape? You probably figured it out thanks to black/oily drips along your engine motor, or a disturbed idle, or unconventional black smoke. These three manifestations are the main signs of a leaking injector. As this problem can bring on more critical engine trouble on your car, we thought we would publish this article content to help you verify the failure of a leaking injector and handle it correctly. To achieve this, we will first of all look into the circumstance of gasoline injectors and then at those of diesel injectors Ford Escape.
Leaking injector on my petrol Ford Escape
It is fundamental to know that the injectors on petrol and diesel engines are distinct, the truth is, the difference in combustion between these two kind of engines makes the injection distinct. The key 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 Escape: The different leaks
It should be known that injector leaks on a Ford Escape equipped with a petrol engine are pretty rare. This is caused by 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 connected 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 occur from the junction with the engine and not with the rail as seen sooner.
Leaking injector on my diesel Ford Escape
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure 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 Ford Escape: The different leaks
In the circumstance of leaking diesel injectors on your Ford Escape, there are three different kind of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform after a while, generally the leak will be at the clamping point. - Injector return leakage:
As its name indicates, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Ford Escape 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 find an air noise and a compression loss. - If after checking you have oil leaking but it does not come from your injectors, we suggest you to consult this article content on the existence of oil leaking on your Ford Escape.
Leaking injector on my Ford Escape, how to fix the leak
And finally, 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 previously, to a worn seal because of the pressures suffered. But think that the pressure in the circuit is gigantic, 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.
Regarding the repair part of your leak, it will frequently be restricted to swapping the seals that have failed:
- Locate the source of the leak
- Take apart the injector in question
- Replace the corresponding seal kit
- Reassemble the set up and tighten with a torque wrench in respect with the manufacturer’s standards.
In all cases, these interventions are not automatically complicated, but if you have the smallest hesitation in the treatment of your injector that leaks on your Ford Escape, we suggest you to get closer to your auto mechanic to avoid any bad handling that could severely harm the condition of your Ford Escape.
