Leaking injector on my petrol Suzuki Across
It is vital to know that the injectors on petrol and diesel engines are distinct, in reality, the difference in combustion between these two kind of engines makes the injection distinct. 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 Suzuki Across: The different leaks
It should be said that injector leaks on a Suzuki Across equipped with a petrol engine are rather rare. This is because of the much lower pressure in the petrol intake systems. However, there are two kind of leaks:
- Leakage from the top of the injector:
It is conceivable that you have a leak from the top of the injector, this is the component that is attached to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:

Leaking injector on my diesel Suzuki Across
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 Suzuki Across: The different leaks
In the circumstance of leaking diesel injectors on your Suzuki Across, there are three several kind of leaks:
- Leakage from the injector inlet:

But think that the pressure in the circuit is monumental, especially on diesel engines. So you will have to take some safety measures:
- Lower the pressure before any work is conducted…
- Covering you to avoid the risk of fuel spillage
- NEVER work on a running diesel engine injector.
Regarding the repair part of your leak, it will regularly be restricted to swapping 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.
In all situations, these interventions are not specifically difficult, but if you have the tiniest uncertainty in the treatment of your injector that leaks on your Suzuki Across, we encourage you to get closer to your motor mechanic to avoid any bad manipulation that could critically harm the condition of your Suzuki Across.
