It is fundamental to know that the injectors on petrol and diesel engines are distinct, the reality is, the difference in combustion between these two types 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 Citroen Berlingo 2: The different leaks
It should be said that injector leaks on a Citroen Berlingo 2 equipped with a petrol engine are pretty infrequent. This is as a result of the much lower pressure in the petrol intake systems. Nevertheless, there are two types of leaks:
- Leakage from the top of the injector:

Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system generates 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.

- Lower the pressure before any work is achieved…
- 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 frequently be limited to changing the seals that have failed:
- Find the source of the leak
