Leaking injector on my petrol Bmw Serie 2 F23

It is fundamental to know that the injectors on petrol and diesel engines are distinct, the truth is, the difference in combustion between these two types of engines makes the injection distinct. The key 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 Bmw Serie 2 F23: The different leaks

It should be known that injector leaks on a Bmw Serie 2 F23 equipped with a petrol engine are pretty infrequent. This is caused by the much lower pressure in the petrol intake systems. Even so, there are two types 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 portion that is attached to the fuel rail, an O-ring will be involved in this.
  • Leak injector of the lower part:
    Finally, 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.

Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure 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 2 F23: The different leaks

In the case of leaking diesel injectors on your Bmw Serie 2 F23, there are three several types of leaks:

  • Leakage from the injector inlet:
    In this case, it is an inlet pipe that will deform in the long run, in most cases the leak will be at the clamping point.
  • Injector return leakage:
    As its name suggests, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Bmw Serie 2 F23 will be the result 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 find an air noise and a compression loss.
  • If after checking you have oil leaking but it does not come from your injectors, we advise you to consult this content page on the existence of oil leaking on your Bmw Serie 2 F23.

Leaking injector on my Bmw Serie 2 F23, how to fix the leak

And finally, 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 endured. 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 restricted to swapping the seals that have failed:

  • Locate the source of the leak
  • Take apart the injector in question
  • Replace the corresponding seal kit
  • Reassemble the set up and tighten with a torque wrench in accordance with the manufacturer’s standards.

In all situations, these interventions are not necessarily complicated, but if you have the slightest hesitation in the treatment of your injector that leaks on your Bmw Serie 2 F23, we advise you to get closer to your repair shop to avoid any bad manipulation that could seriously harm the condition of your Bmw Serie 2 F23.
