In the event you are alert of abnormal symptoms on your automobile, you are right to be worried, because a car represents a huge annual budget and surprising breakdowns don’t lower the costs. So what if you feel as if you have a leaking injector on your Ford Galaxy? You likely figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or uncommon black smoke. These three symptoms are the main signs of a leaking injector. As this problem can bring on more significant engine concerns on your car, we chose to publish 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 circumstance of gasoline injectors and then at those of diesel injectors Ford Galaxy.
Leaking injector on my petrol Ford Galaxy
It is fundamental to know that the injectors on petrol and diesel engines are different, actually, the difference in combustion between these two types of engines makes the injection different. The biggest 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 Galaxy: The different leaks
It should be said that injector leaks on a Ford Galaxy equipped with a petrol engine are rather rare. This is resulting from the much lower pressure in the petrol intake systems. However, there are two types 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 portion 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 Galaxy
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure 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 Galaxy: The different leaks
In the circumstance of leaking diesel injectors on your Ford Galaxy, there are three several types of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform over time, commonly the leak will be at the clamping point. - Injector return leakage:
As its name reveals, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Ford Galaxy 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 experience an air noise and a compression loss. - If after verifying you have oil leaking but it does not come from your injectors, we encourage you to consult this content on the existence of oil leaking on your Ford Galaxy.
Leaking injector on my Ford Galaxy, how to fix the leak
And to finish, we’re going to look at how to fix a leaking injector on your car. Frequently a leak is associated, as we have seen previously, to a worn seal because of the pressures endured. But think that the pressure in the circuit is gigantic, especially on diesel engines. So you will have to take some precautions:
- Lower the pressure before any work is completed…
- 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 limited to replacing the seals that have failed:
- Find out the source of the leak
- Take apart the injector in question
- Change 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 specifically difficult, but if you have the slightest hesitation in the treatment of your injector that leaks on your Ford Galaxy, we encourage you to get closer to your auto mechanic to avoid any bad manipulation that could significantly harm the condition of your Ford Galaxy.
