As this problem can cause more severe engine concerns on your car, we chose to compose this article content to help you confirm the failure of a leaking injector and handle it correctly. To do this, we will initially check out the case of gasoline injectors and then at those of diesel injectors Ford Tourneo.
Leaking injector on my petrol Ford Tourneo
It is vital to know that the injectors on petrol and diesel engines are distinct, the truth is, the difference in combustion between these two sort of engines makes the injection distinct. The biggest 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 Ford Tourneo: The different leaks
It should be said that injector leaks on a Ford Tourneo equipped with a petrol engine are pretty rare. This is resulting from 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 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 part of the injector of your car, this one will occur from the junction with the engine and not with the rail as seen sooner.
Leaking injector on my diesel Ford Tourneo
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 Ford Tourneo: The different leaks
In the case of leaking diesel injectors on your Ford Tourneo, there are three several sort of leaks:
- Leakage from the injector inlet:
In cases like this, it is an inlet pipe that will deform after a while, commonly the leak will be at the clamping point. - Injector return leakage:
As its name indicates, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Ford Tourneo 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 feel an air noise and a compression loss. - If after examining you have oil leaking but it does not come from your injectors, we advise you to browse this article content on the presence of oil leaking on your Ford Tourneo.
Leaking injector on my Ford Tourneo, how to fix the leak
And at last, we’re going to check out how to fix a leaking injector on your car. Frequently a leak is connected, as we have seen previously, to a worn seal due to the pressures suffered. But think that the pressure in the circuit is enormous, especially on diesel engines. So you will have to take some precautions:
- Lower the pressure before any work is conducted…
- 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 limited to changing the seals that have failed:
- Find out the source of the leak
- Take apart 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 cases, these interventions are not specifically very hard, but if you have the smallest uncertainty in the treatment of your injector that leaks on your Ford Tourneo, we advise you to get closer to your auto technician to avoid any bad handling that could seriously harm the condition of your Ford Tourneo.
