In the event you are alert of unusual symptoms on your vehicle, you are right to be concerned, because a car represents a big annual budget and unpredicted malfunctions don’t lower the expenses. So what if you feel like you have a leaking injector on your Jaguar XE? 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 signs of illness are the main signals of a leaking injector. As this failure can bring on more critical engine problems on your car, we decided to prepare this content page to help you confirm the failure of a leaking injector and deal with it properly. To accomplish this, we will initially check out the circumstance of gasoline injectors and then at those of diesel injectors Jaguar XE.
Leaking injector on my petrol Jaguar XE
It is crucial to know that the injectors on petrol and diesel engines are different, actually, 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 Jaguar XE: The different leaks
It should be said that injector leaks on a Jaguar XE equipped with a petrol engine are pretty rare. This is because of the much lower pressure in the petrol intake systems. However, there are two kind 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 portion 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 encounter 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 sooner.
Leaking injector on my diesel Jaguar XE
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system 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 XE: The different leaks
In the circumstance of leaking diesel injectors on your Jaguar XE, there are three several kind of leaks:
- Leakage from the injector inlet:
In cases like this, it is an inlet pipe that will deform over time, 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 XE will be brought on by 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 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 content page on the presence of oil leaking on your Jaguar XE.
Leaking injector on my Jaguar XE, how to fix the leak
And to finish, we’re going to check out 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 caused by the pressures suffered. But think that the pressure in the circuit is enormous, specifically on diesel engines. So you will have to take some 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.
Regarding the repair part of your leak, it will frequently be restricted to swapping 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 respect with the manufacturer’s standards.
In all cases, these interventions are not necessarily complex, but if you have the tiniest hesitation in the treatment of your injector that leaks on your Jaguar XE, we recommend you to get closer to your mechanic to avoid any bad handling that could seriously harm the condition of your Jaguar XE.
