These three signs of illness are the main signs of a leaking injector. As this problem can bring on more critical engine trouble on your car, we made a decision to produce this article content to help you ensure the failure of a leaking injector and handle it correctly. To do this, we will first check out the circumstance of gasoline injectors and then at those of diesel injectors Ford C-max.
Leaking injector on my petrol Ford C-max
It is important to know that the injectors on petrol and diesel engines are different, in reality, the difference in combustion between these two kind of engines makes the injection different. The essential 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 C-max: The different leaks
It should be known that injector leaks on a Ford C-max equipped with a petrol engine are pretty rare. This is because of the much lower pressure in the petrol intake systems. Nevertheless, 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 component that is connected to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
Finally, 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 previously.
Leaking injector on my diesel Ford C-max
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 C-max: The different leaks
In the circumstance of leaking diesel injectors on your Ford C-max, there are three several kind of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform along with time, generally 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 C-max will be the result 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 checking you have oil leaking but it does not come from your injectors, we encourage you to browse this article content on the existence of oil leaking on your Ford C-max.
Leaking injector on my Ford C-max, how to fix the leak
And finally, we’re going to check out how to fix a leaking injector on your car. Oftentimes a leak is associated, as we have seen sooner, to a worn seal because of the pressures endured. But think that the pressure in the circuit is monumental, specifically on diesel engines. So you will have to take some precautions:
- Lower the pressure before any work is conducted…
- 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 oftentimes be restricted to changing the seals that have failed:
- Situate the source of the leak
- Dismantle 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 situations, these interventions are not specifically complicated, but if you have the slightest hesitation in the treatment of your injector that leaks on your Ford C-max, we encourage you to get closer to your auto technician to avoid any bad manipulation that could severely harm the condition of your Ford C-max.
