In the event that you are alert of abnormal signs on your automobile, you are right to be worried, because a car represents a big annual budget and sudden breakdowns don’t lower the bill. So what if you feel as if you have a leaking injector on your Jaguar E-Pace? You most likely figured it out thanks to black/oily drips along your engine unit, or a troubled idle, or abnormal black smoke. These three manifestations are the main indicators of a leaking injector. As this failure can lead to more serious engine concerns on your car, we made a decision to produce this content to help you verify the failure of a leaking injector and handle it properly. To achieve this, we will first look into the case of gasoline injectors and then at those of diesel injectors Jaguar E-Pace.

Leaking injector on my petrol Jaguar E-Pace

It is essential 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 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 Jaguar E-Pace: The different leaks

It should be known that injector leaks on a Jaguar E-Pace equipped with a petrol engine are rather rare. This is because of the much lower pressure in the petrol intake systems. However, 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 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 experience 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 Jaguar E-Pace

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 Jaguar E-Pace: The different leaks

In the case of leaking diesel injectors on your Jaguar E-Pace, there are three several types of leaks:

  • Leakage from the injector inlet:
    In this case, it is an inlet pipe that will deform as time passes, generally the leak will be at the clamping point.
  • Injector return leakage:
    As its name indicates, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Jaguar E-Pace 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 experience an air noise and a compression loss.
  • If after checking you have oil leaking but it does not come from your injectors, we suggest you to read this content on the presence of oil leaking on your Jaguar E-Pace.

Leaking injector on my Jaguar E-Pace, how to fix the leak

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

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

  • Situate the source of the leak
  • Dismantle the injector in question
  • Change the corresponding seal kit
  • Reassemble the assembly and tighten with a torque wrench in accordance with the manufacturer’s standards.

In all situations, these interventions are not automatically very hard, but if you have the slightest hesitation in the treatment of your injector that leaks on your Jaguar E-Pace, we suggest you to get closer to your auto technician to avoid any bad handling that could severely harm the condition of your Jaguar E-Pace.
