In the event that you are aware of unusual signs on your car, you are right to be worried, because a car represents a massive annual budget and sudden breakdowns don’t reduce the expenses. So what if you feel as if you have a leaking injector on your Jaguar F-Pace? You most likely figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or strange black smoke. These three symptoms are the main indicators of a leaking injector. As this failure can bring about more serious engine trouble on your car, we thought we would prepare this content to help you verify the failure of a leaking injector and treat it correctly. To do so, we will first of all take a look at the case of gasoline injectors and then at those of diesel injectors Jaguar F-Pace.
Leaking injector on my petrol Jaguar F-Pace
It is essential to know that the injectors on petrol and diesel engines are distinct, the reality is, the difference in combustion between these two kind of engines makes the injection distinct. 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 Jaguar F-Pace: The different leaks
It should be noted that injector leaks on a Jaguar F-Pace equipped with a petrol engine are pretty infrequent. This is caused by the much lower pressure in the petrol intake systems. Nevertheless, there are two kind 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 component that is connected 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 sooner.
Leaking injector on my diesel Jaguar F-Pace
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 Jaguar F-Pace: The different leaks
In the case of leaking diesel injectors on your Jaguar F-Pace, there are three several kind of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform with time, commonly the leak will be at the clamping point. - Injector return leakage:
As its name reveals, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Jaguar F-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 feel an air noise and a compression loss. - If after verifying you have oil leaking but it does not come from your injectors, we advise you to browse this content on the presence of oil leaking on your Jaguar F-Pace.
Leaking injector on my Jaguar F-Pace, how to fix the leak
And at last, we’re going to take a look at how to fix a leaking injector on your car. Very often a leak is linked, as we have seen previously, to a worn seal caused by the pressures endured. But think that the pressure in the circuit is monumental, especially on diesel engines. So you will have to take some measures:
- Lower the pressure before any work is completed…
- 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 very often be limited to replacing the seals that have failed:
- Situate 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 cases, these interventions are not necessarily very hard, but if you have the smallest uncertainty in the treatment of your injector that leaks on your Jaguar F-Pace, we advise you to get closer to your motor mechanic to avoid any bad manipulation that could severely harm the condition of your Jaguar F-Pace.
