In the event that you are alert of abnormal signs on your automobile, you are right to be worried, because a car represents a massive annual budget and sudden breakdowns don’t reduce the costs. So what if you sense that you have a leaking injector on your Ford F 350 ? You most likely figured it out thanks to black/oily drips along your engine, or a disturbed idle, or strange black smoke. These three signs of illness are the main indicators of a leaking injector. As this failure can lead to more critical engine complications on your car, we decided to write this content to help you validate the failure of a leaking injector and treat it correctly. To do this, we will initially look at the circumstance of gasoline injectors and then at those of diesel injectors Ford F 350 .
Leaking injector on my petrol Ford F 350
It is vital to know that the injectors on petrol and diesel engines are distinct, actually, the difference in combustion between these two kind of engines makes the injection distinct. The main 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 350 : The different leaks
It should be noted that injector leaks on a Ford F 350 equipped with a petrol engine are pretty infrequent. This is because of the much lower pressure in the petrol intake systems. Even so, 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 suffer a leak coming from the lower part of the injector of your car, this one will appear from the junction with the engine and not with the rail as seen previously.
Leaking injector on my diesel Ford F 350
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 F 350 : The different leaks
In the circumstance of leaking diesel injectors on your Ford F 350 , there are three several kind of leaks:
- Leakage from the injector inlet:
In cases like this, 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 reveals, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Ford F 350 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 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 consult this content on the existence of oil leaking on your Ford F 350 .
Leaking injector on my Ford F 350 , how to fix the leak
And at last, we’re going to look at how to fix a leaking injector on your car. Very often a leak is associated, as we have seen previously, to a worn seal caused by the pressures endured. But think that the pressure in the circuit is tremendous, 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.
Concerning the repair part of your leak, it will regularly be restricted to changing the seals that have failed:
- Discover 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 accordance with the manufacturer’s standards.
In all situations, these interventions are not inevitably difficult, but if you have the slightest uncertainty in the treatment of your injector that leaks on your Ford F 350 , 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 350 .
