So what if you feel as if you have a leaking injector on your Land Rover Evoque? You almost certainly figured it out thanks to black/oily drips along your engine motor, or a disturbed idle, or abnormal black smoke. These three signs of illness are the main signs of a leaking injector. As this failure can bring about more critical engine complications on your car, we made a decision to compose this article content to help you verify the failure of a leaking injector and handle it correctly. To do this, we will first of all look into the case of gasoline injectors and then at those of diesel injectors Land Rover Evoque.
Leaking injector on my petrol Land Rover Evoque
It is vital 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 biggest 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 Land Rover Evoque: The different leaks
It should be known that injector leaks on a Land Rover Evoque equipped with a petrol engine are pretty rare. This is due to the much lower pressure in the petrol intake systems. Even so, there are two sort 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 portion 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 encounter a leak coming from the lower portion 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 Land Rover Evoque
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure 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 Land Rover Evoque: The different leaks
In the case of leaking diesel injectors on your Land Rover Evoque, there are three several sort of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform over time, 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 Land Rover Evoque will be caused by 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 verifying you have oil leaking but it does not come from your injectors, we suggest you to consult this article content on the presence of oil leaking on your Land Rover Evoque.
Leaking injector on my Land Rover Evoque, how to fix the leak
And finally, we’re going to look into how to fix a leaking injector on your car. Very often a leak is connected, as we have seen prior to this, to a worn seal as a result of the pressures endured. But think that the pressure in the circuit is tremendous, specifically on diesel engines. So you will have to take some safety measures:
- Lower the pressure before any work is completed…
- Covering 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 very often be limited to replacing the seals that have failed:
- Discover the source of the leak
- Take apart the injector in question
- Replace the corresponding seal kit
- Reassemble the assembly and tighten with a torque wrench in accordance with the manufacturer’s standards.
In all cases, these interventions are not automatically difficult, but if you have the slightest doubt in the treatment of your injector that leaks on your Land Rover Evoque, we suggest you to get closer to your repair shop to avoid any bad handling that could significantly harm the condition of your Land Rover Evoque.
