In cases where you are alert of irregular symptoms on your automobile, you are right to be preoccupied, because a car represents a massive annual budget and unforeseen malfunctions don’t lower the expenses. So what if you sense that you have a leaking injector on your Ford B-max? You almost certainly figured it out thanks to black/oily drips along your engine unit, or a disturbed idle, or unconventional black smoke. These three manifestations are the main symptoms of a leaking injector. As this problem can end up in more severe engine trouble on your car, we chose to write this article to help you verify the failure of a leaking injector and deal with it properly. To do so, we will initially look into the circumstance of gasoline injectors and then at those of diesel injectors Ford B-max.
Leaking injector on my petrol Ford B-max
It is crucial to know that the injectors on petrol and diesel engines are distinct, the reality is, the difference in combustion between these two sort 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 B-max: The different leaks
It should be noted that injector leaks on a Ford B-max equipped with a petrol engine are pretty rare. This is caused by the much lower pressure in the petrol intake systems. However, there are two sort of leaks:
- Leakage from the top of the injector:
It is conceivable 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 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 before.
Leaking injector on my diesel Ford B-max
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system 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 B-max: The different leaks
In the circumstance of leaking diesel injectors on your Ford B-max, there are three different sort 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 relates to the management of the fuel return in the injector, this time the injector that leaks on your Ford B-max 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 annoying, it is the junction between the engine and the injector nose that leaks at a copper seal, you should find an air noise and a compression loss. - If after checking you have oil leaking but it does not come from your injectors, we advise you to browse this article on the existence of oil leaking on your Ford B-max.
Leaking injector on my Ford B-max, how to fix the leak
And finally, we’re going to look into how to fix a leaking injector on your car. Very often a leak is associated, as we have seen sooner, to a worn seal because of 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 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 restricted to changing the seals that have failed:
- Find out the source of the leak
- Dismantle 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 very hard, but if you have the tiniest doubt in the treatment of your injector that leaks on your Ford B-max, we advise you to get closer to your motor mechanic to avoid any bad manipulation that could seriously harm the condition of your Ford B-max.
