Leaking injector on my petrol Bmw Serie 1 F20
It is crucial to know that the injectors on petrol and diesel engines are distinct, in reality, the difference in combustion between these two kind of engines makes the injection distinct. The essential 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 Bmw Serie 1 F20: The different leaks
It should be mentioned that injector leaks on a Bmw Serie 1 F20 equipped with a petrol engine are pretty rare. This is caused by the much lower pressure in the petrol intake systems. Even so, 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 part that is linked to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
Finally, you may experience 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 previously.
Leaking injector on my diesel Bmw Serie 1 F20
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 Bmw Serie 1 F20: The different leaks
In the case of leaking diesel injectors on your Bmw Serie 1 F20, there are three several kind 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:

Leaking injector on my Bmw Serie 1 F20, 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 connected, as we have seen sooner, to a worn seal caused by the pressures suffered. 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 conducted…
- Masking 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 swapping the seals that have failed:
- Discover the source of the leak
- Dismantle 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.
