So what if you think that you have a leaking injector on your Land Rover Freelander? You almost certainly figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or abnormal black smoke. These three signs of illness are the main indicators of a leaking injector. As this problem can bring on more critical engine concerns on your car, we decided to prepare this content to help you confirm the failure of a leaking injector and deal with it properly. To do so, we will initially take a look at the circumstance of gasoline injectors and then at those of diesel injectors Land Rover Freelander.
Leaking injector on my petrol Land Rover Freelander
It is vital to know that the injectors on petrol and diesel engines are different, in reality, the difference in combustion between these two sort of engines makes the injection different. 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 Land Rover Freelander: The different leaks
It should be said that injector leaks on a Land Rover Freelander 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 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 part 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 suffer a leak coming from the lower portion 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 Land Rover Freelander
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system 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 Land Rover Freelander: The different leaks
In the circumstance of leaking diesel injectors on your Land Rover Freelander, there are three several sort of leaks:
- Leakage from the injector inlet:
In cases like this, it is an inlet pipe that will deform along with time, generally the leak will be at the clamping point. - Injector return leakage:
As its name suggests, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Land Rover Freelander 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 encounter 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 browse this content on the existence of oil leaking on your Land Rover Freelander.
Leaking injector on my Land Rover Freelander, how to fix the leak
And to finish, we’re going to take a look at how to fix a leaking injector on your car. Regularly a leak is linked, as we have seen prior to this, to a worn seal caused by the pressures endured. But think that the pressure in the circuit is enormous, especially on diesel engines. So you will have to take some 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 regularly be restricted to replacing 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 difficult, but if you have the smallest doubt in the treatment of your injector that leaks on your Land Rover Freelander, we recommend you to get closer to your motor mechanic to avoid any bad manipulation that could severely harm the condition of your Land Rover Freelander.
