Whenever you are alert of irregular symptoms on your automobile, you are right to be intrigued, because a car represents a massive annual budget and unpredicted breakdowns don’t reduce the bill. So what if you feel as if you have a leaking injector on your Fiat Ducato 2? You likely figured it out thanks to black/oily drips along your engine, or a troubled idle, or strange black smoke. These three manifestations are the main indicators of a leaking injector. As this problem can cause more critical engine complications on your car, we decided to write this article content to help you confirm the failure of a leaking injector and handle it properly. To do so, we will initially take a look at the case of gasoline injectors and then at those of diesel injectors Fiat Ducato 2.

Leaking injector on my petrol Fiat Ducato 2

It is crucial to know that the injectors on petrol and diesel engines are different, the truth is, the difference in combustion between these two types of engines makes the injection different. The biggest 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 Fiat Ducato 2: The different leaks

It should be known that injector leaks on a Fiat Ducato 2 equipped with a petrol engine are pretty rare. This is as a result 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 plausible that you have a leak from the top of the injector, this is the part 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 experience 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 Fiat Ducato 2

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 Fiat Ducato 2: The different leaks

In the case of leaking diesel injectors on your Fiat Ducato 2, 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, 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 Fiat Ducato 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 bothersome, 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 verifying you have oil leaking but it does not come from your injectors, we recommend you to read this article content on the existence of oil leaking on your Fiat Ducato 2.

Leaking injector on my Fiat Ducato 2, how to fix the leak

And to finish, we’re going to take a look at how to fix a leaking injector on your car. Regularly a leak is associated, 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 monumental, specifically on diesel engines. So you will have to take some measures:

  • Lower the pressure before any work is achieved…
  • Covering 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 very often be limited to changing 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 situations, these interventions are not specifically difficult, but if you have the tiniest hesitation in the treatment of your injector that leaks on your Fiat Ducato 2, we recommend you to get closer to your repair shop to avoid any bad manipulation that could critically harm the condition of your Fiat Ducato 2.
