In the event that you are aware of abnormal signs on your vehicle, you are right to be preoccupied, because a car represents a massive annual budget and sudden malfunctions don’t reduce the bill. So what if you feel as if you have a leaking injector on your Suzuki Jimny? You most likely figured it out thanks to black/oily drips along your engine motor, or a disturbed idle, or strange black smoke. These three manifestations are the main indicators of a leaking injector. As this failure can lead to more severe engine concerns on your car, we thought we would write this article to help you ensure the failure of a leaking injector and treat it correctly. To do this, we will initially check out the circumstance of gasoline injectors and then at those of diesel injectors Suzuki Jimny.
Leaking injector on my petrol Suzuki Jimny
It is essential to know that the injectors on petrol and diesel engines are distinct, the truth is, the difference in combustion between these two sort of engines makes the injection distinct. The biggest 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 Jimny: The different leaks
It should be noted that injector leaks on a Suzuki Jimny 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 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 linked to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
Finally, you may experience a leak coming from the lower part of the injector of your car, this one will occur from the junction with the engine and not with the rail as seen previously.
Leaking injector on my diesel Suzuki Jimny
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.
Leaking injector on diesel Suzuki Jimny: The different leaks
In the circumstance of leaking diesel injectors on your Suzuki Jimny, there are three different sort of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform after a while, generally the leak will be at the clamping point. - Injector return leakage:
As its name implies, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Suzuki Jimny will be brought on by an O-ring or its plastic tip that leaks. - Injector base leak:
This injection leak is one of the most annoying, it is the junction between the engine and the injector nose that leaks at a copper seal, you should feel an air noise and a compression loss. - If after examining you have oil leaking but it does not come from your injectors, we encourage you to browse this article on the existence of oil leaking on your Suzuki Jimny.
Leaking injector on my Suzuki Jimny, how to fix the leak
And finally, we’re going to check out 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 gigantic, especially on diesel engines. So you will have to take some measures:
- Lower the pressure before any work is completed…
- Covering 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 very often be restricted to replacing the seals that have failed:
- Situate the source of the leak
- Take apart the injector in question
- Change the corresponding seal kit
- Reassemble the assembly and tighten with a torque wrench in respect with the manufacturer’s standards.
In all cases, these interventions are not necessarily complex, but if you have the tiniest doubt in the treatment of your injector that leaks on your Suzuki Jimny, we encourage you to get closer to your repair shop to avoid any bad manipulation that could significantly harm the condition of your Suzuki Jimny.
