In the event you are aware of irregular signs on your vehicle, you are right to be concerned, because a car represents a huge annual budget and unexpected malfunctions don’t reduce the expenses. So what if you find that you have a leaking injector on your Ford C-max 2? You almost certainly figured it out thanks to black/oily drips along your engine motor, or a disturbed idle, or unconventional black smoke. These three signs of illness are the main indicators of a leaking injector. As this failure can produce more serious engine complications on your car, we chose to compose this article content to help you ensure the failure of a leaking injector and deal with it correctly. To achieve this, we will first of all take a look at the case of gasoline injectors and then at those of diesel injectors Ford C-max 2.

Leaking injector on my petrol Ford C-max 2

It is crucial to know that the injectors on petrol and diesel engines are different, actually, the difference in combustion between these two sort of engines makes the injection different. The key 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 C-max 2: The different leaks

It should be noted that injector leaks on a Ford C-max 2 equipped with a petrol engine are rather infrequent. This is due to the much lower pressure in the petrol intake systems. Even so, there are two sort 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 attached 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 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 C-max 2

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 C-max 2: The different leaks

In the case of leaking diesel injectors on your Ford C-max 2, there are three several sort of leaks:

  • Leakage from the injector inlet:
    In this case, it is an inlet pipe that will deform as time passes, commonly the leak will be at the clamping point.
  • Injector return leakage:
    As its name implies, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Ford C-max 2 will be caused 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 find an air noise and a compression loss.

Leaking injector on my Ford C-max 2, how to fix the leak

And at last, we’re going to take a look at how to fix a leaking injector on your car. Frequently a leak is connected, as we have seen sooner, to a worn seal as a result of the pressures endured. But think that the pressure in the circuit is tremendous, especially on diesel engines. So you will have to take some measures:

  • 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.

Relating to the repair part of your leak, it will regularly be limited to swapping the seals that have failed:

  • Find 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 cases, these interventions are not automatically complicated, but if you have the tiniest uncertainty in the treatment of your injector that leaks on your Ford C-max 2, we recommend you to get closer to your motor mechanic to avoid any bad handling that could significantly harm the condition of your Ford C-max 2.
