Whenever you are aware of abnormal signs on your vehicle, you are right to be worried, because a car represents a huge annual budget and unpredicted malfunctions don’t lower the bill. So what if you feel as if you have a leaking injector on your Maserati Ghibli? You almost certainly figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or abnormal black smoke. These three signs of illness are the main signs of a leaking injector. As this failure can end up in more severe engine problems on your car, we thought we would produce this content to help you confirm the failure of a leaking injector and handle it properly. To accomplish this, we will first of all check out the case of gasoline injectors and then at those of diesel injectors Maserati Ghibli.

Leaking injector on my petrol Maserati Ghibli

It is essential to know that the injectors on petrol and diesel engines are different, in fact, the difference in combustion between these two kind of engines makes the injection different. 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 Maserati Ghibli: The different leaks

It should be known that injector leaks on a Maserati Ghibli equipped with a petrol engine are pretty rare. 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 conceivable that you have a leak from the top of the injector, this is the part that is linked to the fuel rail, an O-ring will be involved in this.
  • Leak injector of the lower part:
    Finally, you may experience a leak coming from the lower portion of the injector of your car, this one will come from the junction with the engine and not with the rail as seen previously.

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 Maserati Ghibli: The different leaks

In the case of leaking diesel injectors on your Maserati Ghibli, there are three different kind of leaks:

  • Leakage from the injector inlet:
    In this case, it is an inlet pipe that will deform with time, in most cases 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 Maserati Ghibli 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 experience 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 consult this content on the presence of oil leaking on your Maserati Ghibli.

Leaking injector on my Maserati Ghibli, how to fix the leak

And finally, we’re going to check out how to fix a leaking injector on your car. Very often a leak is linked, as we have seen sooner, to a worn seal caused by the pressures endured. But think that the pressure in the circuit is gigantic, specifically on diesel engines. So you will have to take some safety 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.

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

  • Find the source of the leak
  • Dismantle 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 cases, these interventions are not automatically very hard, but if you have the smallest uncertainty in the treatment of your injector that leaks on your Maserati Ghibli, we advise you to get closer to your motor mechanic to avoid any bad manipulation that could critically harm the condition of your Maserati Ghibli.
