Whenever you are alert of unusual symptoms on your automobile, you are right to be preoccupied, because a car represents a huge annual budget and unpredicted breakdowns don’t lower the bill. So what if you think that you have a leaking injector on your Bmw X2? You almost certainly figured it out thanks to black/oily drips along your engine unit, or a disturbed idle, or abnormal black smoke. These three signs of illness are the main symptoms of a leaking injector. As this failure can bring on more significant engine problems on your car, we chose to publish this article to help you verify the failure of a leaking injector and deal with it properly. To accomplish this, we will first check out the case of gasoline injectors and then at those of diesel injectors Bmw X2.
Leaking injector on my petrol Bmw X2
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 main 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 X2: The different leaks
It should be known that injector leaks on a Bmw X2 equipped with a petrol engine are rather rare. This is resulting from the much lower pressure in the petrol intake systems. Nevertheless, there are two kind 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 component that is connected to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
Finally, you may suffer 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 before.
Leaking injector on my diesel Bmw X2
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 X2: The different leaks
In the case of leaking diesel injectors on your Bmw X2, there are three several kind of leaks:
- Leakage from the injector inlet:
In cases like this, it is an inlet pipe that will deform as time passes, in most cases the leak will be at the clamping point. - Injector return leakage:
As its name reveals, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Bmw X2 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 bothersome, 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 verifying you have oil leaking but it does not come from your injectors, we encourage you to consult this article on the existence of oil leaking on your Bmw X2.
Leaking injector on my Bmw X2, 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 previously, to a worn seal as a result of the pressures suffered. But think that the pressure in the circuit is enormous, especially on diesel engines. So you will have to take some safety measures:
- Lower the pressure before any work is achieved…
- Covering you to avoid the risk of fuel spillage
- NEVER work on a running diesel engine injector.
Regarding the repair part of your leak, it will very often be restricted to changing the seals that have failed:
- Identify the source of the leak
- Dismantle 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 cases, these interventions are not necessarily complex, but if you have the smallest hesitation in the treatment of your injector that leaks on your Bmw X2, we encourage you to get closer to your repair shop to avoid any bad manipulation that could significantly harm the condition of your Bmw X2.
If perhaps you have any further questions about the Bmw X2, do not hesitate to consult our Bmw X2 category.
