Leaking injector on my petrol Hyundai Veloster
It is fundamental to know that the injectors on petrol and diesel engines are distinct, in fact, the difference in combustion between these two sort of engines makes the injection distinct. The essential 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 Hyundai Veloster: The different leaks
It should be noted that injector leaks on a Hyundai Veloster equipped with a petrol engine are pretty rare. This is due to 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 plausible 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:

- Lower the pressure before any work is carried out…
- 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 oftentimes be restricted to changing the seals that have failed:
- Find out the source of the leak
- Take apart the injector in question
