In cases where you are informed of irregular signs on your vehicle, you are right to be concerned, because a car represents a big annual budget and unforeseen malfunctions don’t lower the costs. So what if you feel as if you have a leaking injector on your Jaguar F-Type? You most likely figured it out thanks to black/oily drips along your engine, or a troubled idle, or abnormal black smoke. These three manifestations are the main indicators of a leaking injector. As this problem can end up in more critical engine complications on your car, we thought we would publish this content to help you ensure the failure of a leaking injector and handle it properly. To accomplish this, we will initially look into the circumstance of gasoline injectors and then at those of diesel injectors Jaguar F-Type.

Leaking injector on my petrol Jaguar F-Type

It is important to know that the injectors on petrol and diesel engines are distinct, actually, the difference in combustion between these two sort of engines makes the injection distinct. The main 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 Jaguar F-Type: The different leaks

It should be mentioned that injector leaks on a Jaguar F-Type equipped with a petrol engine are pretty rare. This is caused by the much lower pressure in the petrol intake systems. However, there are two sort 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 portion 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 suffer a leak coming from the lower part of the injector of your car, this one will come from the junction with the engine and not with the rail as seen previously.

Leaking injector on my diesel Jaguar F-Type

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 Jaguar F-Type: The different leaks

In the circumstance of leaking diesel injectors on your Jaguar F-Type, there are three several sort of leaks:

  • Leakage from the injector inlet:
    In this instance, it is an inlet pipe that will deform after a while, usually 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 Jaguar F-Type 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 experience an air noise and a compression loss.
  • If after examining you have oil leaking but it does not come from your injectors, we recommend you to read this content on the existence of oil leaking on your Jaguar F-Type.

Leaking injector on my Jaguar F-Type, how to fix the leak

And at last, we’re going to look into how to fix a leaking injector on your car. Frequently a leak is linked, as we have seen prior to this, to a worn seal because of the pressures endured. But think that the pressure in the circuit is gigantic, specifically on diesel engines. So you will have to take some precautions:

  • 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.

Concerning the repair part of your leak, it will regularly be restricted to replacing the seals that have failed:

  • Locate 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 complex, but if you have the slightest uncertainty in the treatment of your injector that leaks on your Jaguar F-Type, we recommend you to get closer to your auto technician to avoid any bad manipulation that could severely harm the condition of your Jaguar F-Type.
