In cases where you are alert of irregular symptoms on your vehicle, you are right to be preoccupied, because a car represents a huge annual budget and unforeseen breakdowns don’t reduce the costs. So what if you feel like you have a leaking injector on your Ford F 550? You almost certainly figured it out thanks to black/oily drips along your engine unit, or a disturbed idle, or unusual black smoke. These three manifestations are the main indicators of a leaking injector. As this failure can end up in more severe engine complications on your car, we thought we would compose this article content to help you validate the failure of a leaking injector and deal with it properly. To accomplish this, we will first of all look at the case of gasoline injectors and then at those of diesel injectors Ford F 550.
Leaking injector on my petrol Ford F 550
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 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 F 550: The different leaks
It should be said that injector leaks on a Ford F 550 equipped with a petrol engine are pretty infrequent. This is caused by 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 linked 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 F 550
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 F 550: The different leaks
In the case of leaking diesel injectors on your Ford F 550, there are three different kind of leaks:
- Leakage from the injector inlet:
In cases like this, it is an inlet pipe that will deform 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 F 550 will be brought on 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 checking you have oil leaking but it does not come from your injectors, we recommend you to read this article content on the presence of oil leaking on your Ford F 550.
Leaking injector on my Ford F 550, how to fix the leak
And at last, we’re going to look at how to fix a leaking injector on your car. Regularly a leak is linked, as we have seen previously, to a worn seal caused by 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…
- Masking you to avoid the risk of fuel spillage
- NEVER work on a running diesel engine injector.
Concerning the repair part of your leak, it will frequently be limited to swapping the seals that have failed:
- Situate 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 accordance with the manufacturer’s standards.
In all situations, these interventions are not automatically complex, but if you have the smallest uncertainty in the treatment of your injector that leaks on your Ford F 550, we recommend you to get closer to your motor mechanic to avoid any bad handling that could significantly harm the condition of your Ford F 550.
