Leaking injector on my petrol Acura ILX
It is important to know that the injectors on petrol and diesel engines are different, in reality, the difference in combustion between these two kind of engines makes the injection different. 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 Acura ILX: The different leaks
It should be noted that injector leaks on a Acura ILX equipped with a petrol engine are pretty infrequent. This is caused by the much lower pressure in the petrol intake systems. However, 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 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 experience 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 previously.
Leaking injector on my diesel Acura ILX
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 Acura ILX: The different leaks
In the case of leaking diesel injectors on your Acura ILX, there are three different kind of leaks:
- Leakage from the injector inlet:

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 Acura ILX 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 annoying, 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 verifying 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 Acura ILX.
Leaking injector on my Acura ILX, how to fix the leak

But think that the pressure in the circuit is gigantic, especially on diesel engines. So you will have to take some safety measures:
- Lower the pressure before any work is done…
- 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 very often be restricted to replacing the seals that have failed:
- Situate the source of the leak
- Take apart 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.
