Leaking injector on my petrol Peugeot Boxer 2
It is crucial to know that the injectors on petrol and diesel engines are different, the reality is, the difference in combustion between these two sort of engines makes the injection different. The key 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 Peugeot Boxer 2: The different leaks
It should be mentioned that injector leaks on a Peugeot Boxer 2 equipped with a petrol engine are pretty infrequent. This is caused by 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 possible 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:

Leaking injector on my diesel Peugeot Boxer 2
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 Peugeot Boxer 2: The different leaks
In the case of leaking diesel injectors on your Peugeot Boxer 2, there are three several sort of leaks:
- Leakage from the injector inlet:

Leaking injector on my Peugeot Boxer 2, how to fix the leak
And finally, we’re going to take a look at how to fix a leaking injector on your car. Oftentimes a leak is linked, as we have seen sooner, to a worn seal caused by the pressures endured. But think that the pressure in the circuit is tremendous, especially on diesel engines. So you will have to take some 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.
Relating to the repair part of your leak, it will oftentimes be restricted to changing the seals that have failed:
- Situate the source of the leak
- Dismantle the injector in question
- Change the corresponding seal kit
- Reassemble the set up and tighten with a torque wrench in accordance with the manufacturer’s standards.
In all situations, these interventions are not inevitably very hard, but if you have the slightest uncertainty in the treatment of your injector that leaks on your Peugeot Boxer 2, we encourage you to get closer to your motor mechanic to avoid any bad manipulation that could significantly harm the condition of your Peugeot Boxer 2.
