In the event you are informed of unusual symptoms on your automobile, you are right to be worried, because a car represents a huge annual budget and unpredicted breakdowns don’t reduce the costs. So what if you find that you have a leaking injector on your Ford Transit? You likely figured it out thanks to black/oily drips along your engine, or a disturbed idle, or uncommon black smoke. These three symptoms are the main symptoms of a leaking injector. As this problem can cause more critical engine concerns on your car, we thought we would prepare this content to help you ensure the failure of a leaking injector and treat it correctly. To accomplish this, we will first of all look at the circumstance of gasoline injectors and then at those of diesel injectors Ford Transit.

Leaking injector on my petrol Ford Transit

It is important to know that the injectors on petrol and diesel engines are distinct, the reality is, the difference in combustion between these two types of engines makes the injection distinct. 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 Transit: The different leaks

It should be mentioned that injector leaks on a Ford Transit equipped with a petrol engine are rather infrequent. This is because of the much lower pressure in the petrol intake systems. Even so, there are two types 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:
    Finally, you may suffer a leak coming from the lower part of the injector of your car, this one will occur from the junction with the engine and not with the rail as seen before.

Leaking injector on my diesel Ford Transit

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 Transit: The different leaks

In the circumstance of leaking diesel injectors on your Ford Transit, there are three different types of leaks:

  • Leakage from the injector inlet:
    In this instance, it is an inlet pipe that will deform along with time, in most cases the leak will be at the clamping point.
  • Injector return leakage:
    As its name reveals, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Ford Transit 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 find an air noise and a compression loss.
  • If after examining you have oil leaking but it does not come from your injectors, we advise you to consult this content on the existence of oil leaking on your Ford Transit.

Leaking injector on my Ford Transit, 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 associated, as we have seen previously, to a worn seal due to the pressures endured. But think that the pressure in the circuit is enormous, especially on diesel engines. So you will have to take some measures:

  • Lower the pressure before any work is carried out…
  • 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 oftentimes be restricted to changing the seals that have failed:

  • Find out 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 necessarily very hard, but if you have the tiniest uncertainty in the treatment of your injector that leaks on your Ford Transit, we advise you to get closer to your repair shop to avoid any bad handling that could critically harm the condition of your Ford Transit.
