In cases where you are informed of unusual symptoms on your car, you are right to be worried, because a car represents a huge annual budget and surprising malfunctions don’t reduce the bill. So what if you feel as if you have a leaking injector on your Ford Ranger? You almost certainly figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or strange black smoke. These three symptoms are the main symptoms of a leaking injector. As this troubles can end up in more critical engine trouble on your car, we decided to compose this article to help you validate the failure of a leaking injector and handle it correctly. To accomplish this, we will first of all check out the case of gasoline injectors and then at those of diesel injectors Ford Ranger.
Leaking injector on my petrol Ford Ranger
It is essential to know that the injectors on petrol and diesel engines are distinct, in fact, the difference in combustion between these two kind of engines makes the injection distinct. The essential 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 Ranger: The different leaks
It should be said that injector leaks on a Ford Ranger equipped with a petrol engine are rather infrequent. This is resulting from 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 possible 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 suffer a leak coming from the lower part of the injector of your car, this one will come from the junction with the engine and not with the rail as seen before.
Leaking injector on my diesel Ford Ranger
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure creates 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 Ranger: The different leaks
In the case of leaking diesel injectors on your Ford Ranger, there are three several kind 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 implies, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Ford Ranger 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 troublesome, it is the junction between the engine and the injector nose that leaks at a copper seal, you should feel 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 article on the presence of oil leaking on your Ford Ranger.
Leaking injector on my Ford Ranger, how to fix the leak
And to finish, we’re going to check out how to fix a leaking injector on your car. Frequently a leak is connected, as we have seen prior to this, to a worn seal due to the pressures endured. But think that the pressure in the circuit is tremendous, especially on diesel engines. So you will have to take some safety 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.
Relating to the repair part of your leak, it will oftentimes be restricted to swapping the seals that have failed:
- Find out the source of the leak
- Dismantle the injector in question
- Change the corresponding seal kit
- Reassemble the assembly and tighten with a torque wrench in accordance with the manufacturer’s standards.
In all cases, these interventions are not necessarily difficult, but if you have the tiniest uncertainty in the treatment of your injector that leaks on your Ford Ranger, we recommend you to get closer to your mechanic to avoid any bad handling that could seriously harm the condition of your Ford Ranger.
