Leaking injector on my petrol Acura TLX
It is vital to know that the injectors on petrol and diesel engines are distinct, the reality is, the difference in combustion between these two sort 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 Acura TLX: The different leaks
It should be known that injector leaks on a Acura TLX equipped with a petrol engine are rather rare. This is caused by 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 possible 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 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 previously.
Leaking injector on my diesel Acura TLX
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure produces 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 TLX: The different leaks
In the circumstance of leaking diesel injectors on your Acura TLX, there are three different sort of leaks:
- Leakage from the injector inlet:

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 encourage you to read this article on the presence of oil leaking on your Acura TLX.
Leaking injector on my Acura TLX, how to fix the leak
And finally, we’re going to look into how to fix a leaking injector on your car. Regularly a leak is linked, as we have seen previously, to a worn seal caused by the pressures endured. But think that the pressure in the circuit is gigantic, specifically on diesel engines. So you will have to take some safety measures:
- Lower the pressure before any work is completed…
- 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:
- Discover 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 respect with the manufacturer’s standards.
