Leaking injector on my petrol Opel Vivaro
It is vital to know that the injectors on petrol and diesel engines are different, the truth is, the difference in combustion between these two sort 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 Opel Vivaro: The different leaks
It should be known that injector leaks on a Opel Vivaro equipped with a petrol engine are pretty infrequent. This is due to the much lower pressure in the petrol intake systems. Nevertheless, 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 portion that is attached to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:

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 conducted…
- Masking you to avoid the risk of fuel spillage
- NEVER work on a running diesel engine injector.
Concerning the repair part of your leak, it will oftentimes be limited to swapping the seals that have failed:
- Discover the source of the leak
- Dismantle the injector in question
